| 2 | Heteroatoms-doped carbon nanocages with enhanced dipolar and defective polarization toward light-weight microwave absorbers显示文摘Light-weight and exceptional microwave absorption are two vital characteristics for microwave absorbers in practical applications,but still face challenges.Herein,we employ a sacrificial template strategy to fabricate heteroatoms-doped carbon nanocages(CNs)via chemical vapor deposition,in which heteroatoms are simultaneously doped into the carbon frameworks by bubbling flowing source liquid.Compared with CNs,doped heteroatoms,accompanied with the inevitably defective arrangements in the lattice,not only decrease the electrical conductivity and balance the impedance characteristics,but also introduce structuralchemical defects and trigger dominant dipolar/defect polarization.As a result,both the minimum reflection loss(R_(L,min))and effective absorption bandwidth(EAB)greatly increase at an ultralow filler loading of 5 wt.%owing to internal hollow void and high specific surface area.The R_(L,min) values reach−53.6,−43.2,and−50.1 dB for N-CNs,S-CNs,and N,S-CNs with the corresponding EAB of 4.9,2.5,and 3.1 GHz,respectively.Furthermore,this work provides an effective strategy for the construction of heteroatoms-doped hollow carbon frameworks in large-scale production and the obtained doped carbon nanocages can be used as light-weight and high-performance microwave absorbers. | Hanxiao Xu Guozheng Zhang Yi Wang Yiruo Wang Huanlei Wang Ying Huang Panbo Liu | 2022 | Nano Research2022,15,10: | 2 |
| 3 | Engineering core–shell Co_(9)S_(8)/Co nanoparticles on reduced graphene oxide: Efficient bifunctional Mott–Schottky electrocatalysts in neutral rechargeable Zn–Air batteries显示文摘It is significant for the rational construction of the high–efficient bifunctional electrocatalysts for in–depth understandings of how to improve the electron transfer and ion/oxygen transport in catalyzing oxygen reduction reaction and oxygen evolution reaction(ORR and OER),but still full of vital challenges.Herein,we synthesize the novel“three–in–one”catalyst that engineers core–shell Mott–Schottky Co_(9)S_(8)/Co heterostructure on the defective reduced graphene oxide(Co_(9)S_(8)/Co–rGO).The Co_(9)S_(8)/Co–rGO catalyst exhibits abundant Mott–Schottky heterogeneous–interfaces,the well–defined core–shell nanostructure as well as the defective carbon architecture,which provide the multiple guarantees for enhancing the electron transfer and ion/oxygen transport,thus boosting the catalytic ORR and OER activities in neutral electrolyte.As expected,the integrated core–shell Mott–Schottky Co_(9)S_(8)/Co–rGO catalyst delivers the most robust and efficient rechargeable ZABs performance in neutral solution electrolytes accompanied with a power density of 59.5 mW cm^(-2) and superior cycling stability at 5 mA cm^(-2) over 200 h.This work not only emphasizes the rational designing of the high–efficient bifunctional oxygen catalysts from the fundamental understanding of accelerating the electron transfer and ion/oxygen transport,but also sheds light on the practical application prospects in more friendly environmentally neutral rechargeable ZABs. | Xingkun Wang Guangming Zhan Yurou Wang Yan Zhang Jian Zhou Ren Xu Huiyu Gai Huanlei Wang Heqing Jiang Minghua Huang | 2022 | Journal of Energy Chemistry2022,31,5: | 2 |
| 4 | Computed tomography of the acoustic nonlinearity parameter B/A for biological tissues via difference frequency wave from a parametric array in reflection mode显示文摘Based on the finite amplitude insert-substitu- tion method, a novel technique to reconstruct the acoustic nonlinear parameter B/A tomography for biological tissues in reflection mode via the difference frequency wave generated by a parametric array is developed in this paper. An experimental system is established, and the beam pattern of the difference frequency wave is measured and compared with that excited directly from a transmitter at the same frequency. B/A tomography for several biological tissues including normal and pathological tissues, is experimentally obtained with satisfying quality. Results indicate that B/A imaging using this mode may become a novel modality in ultrasonic diagnosis. | WANG Huanlei, ZHU Xiaofeng, GONG Xiufen & ZHANG Dong State Key Laboratory of Modern Acoustics, Institute of Acoustics, Nanjing University, Nanjing 210093, China | 2003 | Chinese Science Bulletin2003,48,22: | 1 |

| 6 | Sulfur and nitrogen codoped cyanoethyl cellulose-derived carbon with superior gravimetric and volumetric capacity for potassium ion storage显示文摘We fabricated sulfur and nitrogen codoped cyanoethyl cellulose-derived carbons(SNCCs)with state-of-the-art electrochemical performance for potassium ion battery(PIB)and potassium ion capacitor(PIC)anodes.At 0.2,0.5,1,2,5,and 10 A g−1,the SNCC shows reversible capacities of 369,328,249,208,150,and 121 mA h g−1,respectively.Due to a high packing density of 1.01 g cm^(−3),the volumetric capacities are also uniquely favorable,being 373,331,251,210,151,and 122 mA h cm^(−3)at these currents,respectively.SNCC also shows promising initial Coulombic efficiency of 69.0%and extended cycling stability with 99.8%capacity retention after 1000 cycles.As proof of principle,an SNCC-based PIC is fabricated and tested,achieving 94.3Wh kg^(−1)at 237.5Wkg^(−1)and sustaining over 6000 cycles at 30 A g−1 with 84.5%retention.The internal structure of S and N codoped SNCC is based on highly dilated and defective graphene sheets arranged into nanometer-scale walls.Using a baseline S-free carbon for comparison(termed NCC),the role of S doping and the resultant dilated structure was elucidated.According to galvanostatic intermittent titration technique and electrochemical impedance spectroscopy analyses,as well as COMSOL simulations,this structure promotes rapid solid-state diffusion of potassium ions and a solid electrolyte interphase that is stable during cycling.X-ray diffraction was used to probe the ion storage mechanisms in SNCC,establishing the role of reversible potassium intercalation and the presence of KC36,KC24,and KC8 phases at low voltages. | Guangzeng Cheng Wenzhe Zhang Wei Wang Huanlei Wang Yixian Wang Jing Shi Jingwei Chen Shuai Liu Minghua Huang David Mitlin | 2022 | Carbon Energy2022,4,5: | 1 |
| 7 | Identifying Heteroatomic and Defective Sites in Carbon with Dual-Ion Adsorption Capability for High Energy and Power Zinc Ion Capacitor显示文摘Aqueous zinc-based batteries(AZB s)attract tremendous attention due to the abundant and rechargeable zinc anode.Nonetheless,the requirement of high energy and power densities raises great challenge for the cathode development.Herein we construct an aqueous zinc ion capacitor possessing an unrivaled combination of high energy and power characteristics by employing a unique dual-ion adsorption mechanism in the cathode side.Through a templating/activating co-assisted carbonization procedure,a routine protein-rich biomass transforms into defect-rich carbon with immense surface area of 3657.5 m^(2) g^(-1) and electrochemically active heteroatom content of 8.0 at%.Comprehensive characterization and DFT calculations reveal that the obtained carbon cathode exhibits capacitive charge adsorptions toward both the cations and anions,which regularly occur at the specific sites of heteroatom moieties and lattice defects upon different depths of discharge/charge.The dual-ion adsorption mechanism endows the assembled cells with maximum capacity of 257 mAh g^(-1) and retention of72 mAh g^(-1) at ultrahigh current density of 100 A g^(-1)(400 C),corresponding to the outstanding energy and power of 168 Wh kg^(-1)and 61,700 W kg^(-1).Furthermore,practical battery configurations of solid-state pouch and cable-type cells display excellent reliability in electrochemistry as flexible and knittable power sources. | Wenjie Fan Jia Ding Jingnan Ding Yulong Zheng Wanqing Song Jiangfeng Lin Caixia Xiao Cheng Zhong Huanlei Wang Wenbin Hu | 2021 | Nano-Micro Letters2021,13,4: | 1 |
| 8 | Engineering adjacent Fe_(3)C as proton-feeding centers to single Fe sites enabling boosted oxygen reduction reaction kinetics for robust Zn-air batteries at high current densities显示文摘Oxygen reduction reaction(ORR)plays an important role in the next-generation energy storage technologies,whereas it involves the sluggish and complicated proton-coupled electron transfer(PCET)steps that greatly limit the ORR kinetics.Therefore,it is urgent to construct an efficient catalyst that could simultaneously achieve the rapid oxygen-containing intermediates conversion and fast PCET process but remain challenging.Herein,the adjacent Fe_(3)C nanoparticles coupling with single Fe sites on the bubble-wrap-like porous N-doped carbon(Fe_(3)C@FeSA-NC)were deliberately constructed.Theoretical investigations reveal that the adjacent Fe_(3)C nanoparticles speed up the water dissociation and serve as proton-feeding centers for boosting the ORR kinetics of single Fe sites.Benefiting from the synergistic effect of the Fe_(3)C and single Fe sites,the Fe_(3)C@FeSA-NC affords an excellent half-wave potential of 0.88 V,and enables the assembled Zn-air batteries with the high peak power density of 164.5 mW·cm^(-2)and long-term stability of over 200 h at high current densities at 50 mA·cm^(-2).This work clarifies the mechanism for improving ORR kinetics of single atomic sites by engineering the adjacent proton-feeding centers,shedding light on the rational design of cost-effective electrocatalysts for energy conversion and storage technologies. | Canhui Zhang Xingkun Wang Kai Song Kaiyue Chen Shuixing Dai Huanlei Wang Minghua Huang | 2023 | Nano Research2023,16,7: | 1 |

| 11 | Controllable Ni/NiO interface engineering on N-doped carbon spheres for boosted alkaline water-to-hydrogen conversion by urea electrolysis显示文摘Interface engineering has gradually attracted substantial research interest in constructing active bifunctional catalysts toward urea electrolysis.The fundamental understanding of the crystallinity transition of the components on both sides of the interface is extremely significant for realizing controllable construction of catalysts through interface engineering,but it still remains a challenge.Herein,the Ni/NiO heterogenous nanoparticles are successfully fabricated on the porous N-doped carbon spheres by a facile hydrothermal and subsequent pyrolysis strategy.And for the first time we show the experimental observation that the Ni/NiO interface can be fine-tuned via simply tailoring the heating rate during pyrolysis process,in which the crystalline/amorphous or crystalline/crystalline Ni/NiO heterostructure is deliberately constructed on the porous N-doped carbon spheres(named as CA-Ni/NiO@NCS or CC-Ni/NiO@NCS,respectively).By taking advantage of the unique porous architecture and the synergistic effect between crystalline Ni and amorphous NiO,the well-designed CA-Ni/NiO@NCS displays more remarkable urea oxidation reaction(UOR)and hydrogen evolution reaction(HER)activity than its crystalline/crystalline counterpart of CC-Ni/NiO@NCS.Particularly,the whole assembled two-electrode electrolytic cell using the elaborate CANi/NiO@NCS both as the anode and cathode can realize the current density of 10 mA·cm^(−2)at a super low voltage of 1.475 V(264 mV less than that of pure water electrolysis),as well as remarkable prolonged stability over 63 h.Besides,the H_(2)evolution driven by an AA battery and a commercial solar cell is also studied to enlighten practical applications for the future. | Xiujuan Xu Xianbiao Hou Puyu Du Canhui Zhang Shucong Zhang Huanlei Wang Arafat Toghan Minghua Huang | 2022 | Nano Research2022,15,8: | 0 |
| 12 | All-cellulose-based quasi-solid-state supercapacitor with nitrogen and boron dual-doped carbon electrodes exhibiting high energy density and excellent cyclic stability显示文摘The key to construct high-energy supercapacitors is to maximize the capacitance of electrode and the voltage of the device. Realizing this purpose by utilizing sustainable and low-cost resources is still a big challenge. Herein, N, B co-doped carbon nanosheets are obtained through the proposed dual-template assisted approach by using methyl cellulose as the precursor. Due to the synergistic effects form the high surface area with the hierarchical porous structure, N/B dual doping, and a high degree of graphitization, the resultant carbon electrode exhibits a high capacitance of 572 F g^(-1)at 0.5 A g^(-1)and retains 281 F g^(-1)at 50 A g^(-1)in an acidic electrolyte. Furthermore, the symmetric device assembled using bacterial cellulose-based gel polymer electrolyte can deliver high energy density of 43 W h kg^(-1)and excellent cyclability with 97.8% capacity retention after 20 000 cycles in “water in salt” electrolyte. This work successfully realizes the fabrication of high-performance allcellulose-based quasi-solid-state supercapacitors, which brings a cost-effective insight into jointly designing electrodes and electrolytes for supporting highly efficient energy storage. | Kaixuan Li Ping Li Zining Sun Jing Shi Minghua Huang Jingwei Chen Shuai Liu Zhicheng Shi Huanlei Wang | 2023 | Green Energy & Environment2023,8,4: | 0 |
| 13 | Order-structuredsolid-stateelectrolytes显示文摘Solid-state electrolytes(SSEs)are recognized as attractive candidates to real-ize safe and high-energy-density lithium metal batteries(LMBs).However,the practical application of SSEs still faces challenges such as insufficient room-temperature ionic conductivity,unsatisfactory mechanical properties,and large internal resistance.Extensive research efforts have been made to explore new electrochemistry and technologies to address those challenges.Among them,the construction of order-structured SSEs has emerged as a promising strategy.The anisotropic behavior induced by the orientation offers SSEs with desired properties targeting specific functions,and therefore the rational design of the order-structured SSE provides an alternative solution to achieve an ideal SSE.This review discusses the structure-property correlation of SSEs,and then sum-marizes the design strategies to construct order-structured SSEs.Finally,the current challenges and possible future research directions for order-structured SSEs for scalable high-energy-density LMBs are presented. | Jingyi Wu Zhixiang Rao Huanlei Wang Yunhui Huang | 2022 | SusMat2022,2,6: | 0 |
| 14 | Microzone-explosion synthesis of porous carbon electrodes for advanced aqueous solid-state supercapacitors with a high-voltage gel electrolyte显示文摘A new microzone-combustion synthesis is proposed for preparing S, N-doped hierarchically porous carbons(CAC-CN) with a novel mixed microstructure of sp~2 short-range order area and sp~3 defective area,achieving a coexistence of high conductivity and high capacitance as well as good access for electrolyte.By engineering ‘‘water in salts' into a polymer matrix, a high-voltage(2.5 V) aqueous gel electrolyte(HGWIS) is prepared and used to construct an aqueous solid-state SCs by in situ polymerization between the electrodes. The good match of CAC-CN electrode and HG-WIS electrolyte endows the assembled devices with superior high energy density and excellent capacitance retention, also a good temperature robustness, as well a high flexibility in 0-180° bending cycles. This study indicates that the collaborative design strategy of electrode materials and electrolyte would be great potential in exploring advanced aqueous solid-state SCs. | Yongxu Du Wei Liu Yongpeng Cui Hongguang Fan Yuan Zhang Tianqi Wang Huanlei Wang Yongcheng Jin Shuang Liu Wenting Feng Ming Chen | 2021 | Journal of Energy Chemistry2021,30,9: | 0 |
| 15 | Interface engineering of NiSe_(2) nanowrinkles/Ni_(5)P_(4)nanorods for boosting urea oxidation reaction at large current densities显示文摘Deliberate modulation of the electronic structure via interface engineering is one of promising perspectives to build advanced catalysts for urea oxidation reaction(UOR)at high current densities.However,it still remains some challenges originating from the intrinsically sluggish UOR dynamics and the high energy barrier for urea adsorption.In response,we report the coupled NiSe_(2)nanowrinkles with Ni_(5)P_(4)nanorods heterogeneous structure onto Ni foam(denoted as NiSe_(2)@Ni_(5)P_(4)/NF)through successive phosphorization and selenization strategy,in which the produced closely contacted interface could provide high-flux electron transfer pathways.Theoretical findings decipher that the fast charge transfer takes place at the interfacial region from Ni_(5)P_(4)to NiSe_(2),which is conducive to optimizing adsorption energy of urea molecules.As expected,the well-designed NiSe_(2)@Ni_(5)P_(4)/NF only requires the low potential of 1.402 V at the current density of 500 mA·cm^(-2).More importantly,a small Tafel slope of 27.6 mV·dec^(-1),a high turnover frequency(TOF)value of 1.037 s^(-1)as well as the prolonged stability of 950 h at the current density of 100 mA·cm^(-2)are also achieved.This study enriches the understanding on the electronic structure modulation via interface engineering and offers bright prospect to design advanced UOR catalysts. | Jinyang Li Xiujuan Xu Xianbiao Hou Shucong Zhang Ge Su Weiqian Tian Huanlei Wang Minghua Huang Arafat Toghan | 2023 | Nano Research2023,16,7: | 0 |
