| 1 | Coupling of ultrasmall and small CoxP nanoparticles confined in porous SiO2 matrix for a robust oxygen evolution reaction显示文摘Rational design of electrocatalysts is important for a sustainable oxygen evolution reaction(OER).It is still a huge challenge to engineer active sites in multi-sizes and multi-components simultaneously.Here,a series of CoxP nanoparticles(NPs)confined in an SiO2matrix(SiO2/CoxP)is designed and synthesized as OER electrocatalysts.The phosphorization of the hydrolyzed Co-phyllosilicate promotes the formation of ultrasmall and small Co2P and CoP.These are firmly confined in the SiO2matrix.The coupling of multi-size and multi-component CoxP catalysts can regulate reaction kinetics and electron transfer ability,enrich the active sites,and eventually promote the intrinsic OER activity.The SiO2matrix provides abundant porous structure and oxygen vacancies,and these facilitate the exposure of active sites and improve conductivity.Because of the synergy and interplay of multisized/component CoxP NPs and the porous SiO2matrix,the unique SiO2/CoxP heterostructure exhibits low overpotential(293 m V@10 mA cm-2),and robust stability(decay 12 mV after 5000 CV cycles,97.4%of initial current after 100 h chronoamperometric)for the OER process,exceeding many advanced metal phosphide electrocatalysts.This work provides a novel tactic to design low-cost,simple,and highly efficient OER electrocatalysts. | Xiaojun Zeng Haiqi Zhang Xiaofeng Zhang Qingqing Zhang Yunxia Chen Ronghai Yu Martin Moskovits | 2022 | Nano Materials Science2022，4，4： | 2 |
| 2 | Progress and challenges of ceramics for supercapacitors显示文摘Supercapacitors(SCs)are one of the most promising electrical energy storage technologies systems due to their fast storage capability,long cycle stability,high power density,and environmental friendliness.Enormous research has focused on the design of nanomaterials to achieve low cost,highly efficient,and stable electrodes.Ceramic materials provide promising candidates for SCs electrodes.However,the low specific surface area and relatively low surface activity severely hinder the SCs performance of ceramic materials.Therefore,the basic understanding of ceramic materials,the optimization strategy,and the research progress of ceramic electrodes are the key steps to enable good electrical conductivity and excellent electron transport capabilities,and realize economically feasible ceramic electrodes in industry.Herein,we review recent achievements in manufacturing the ceramic electrodes for SCs,including metal oxide ceramics,multi-elemental oxide ceramics,metal hydroxide ceramics,metal sulfide ceramics,carbon-based ceramics,carbide and nitride ceramics,and other special ceramics(MXene).We focus on the unique and key factors in the component and structural design of ceramic electrodes,which correlate them with SCs performance.In addition,the current technical challenges and perspectives of ceramic electrodes for SCs are also discussed. | Xiaojun Zeng Hanbin Song Zong-Yang Shen Martin Moskovits | 2021 | Journal of Materiomics2021，7，6： | 2 |

| 8 | Nanobridged rhombic antennas supporting both dipolar and high-order plasmonic modes with spatially superimposed hotspots in the mid-infrared显示文摘Mid-infrared antennas(MIRAs)support highly-efficient optical resonance in the infrared,enabling multiple applications,such as surface-enhanced infrared absorption(SEIRA)spectroscopy and ultrasensitive mid-infrared detection.However,most MIRAs such as dipolar-antenna structures support only narrow-band dipolar-mode resonances while high-order modes are usually too weak to be observed,severely limiting other useful applications that broadband resonances make possible.In this study,we report a multiscale nanobridged rhombic antenna(NBRA)that supports two dominant reson-ances in the MIR,including a charge-transfer plasmon(CTP)band and a bridged dipolar plasmon(BDP)band which looks like a quadruple resonance.These assignments are evidenced by scattering-type scanning near-field optical micro-scopy(s-SNOM)imaging and electromagnetic simulations.The high-order mode only occurs with nanometer-sized bridge(nanobridge)linked to the one end of the rhombic arm which mainly acts as the inductance and the resistance by the circuit analysis.Moreover,the main hotspots associated with the two resonant bands are spatially superimposed,en-abling boosting up the local field for both bands by multiscale coupling.With large field enhancements,multiband detec-tion with high sensitivity to a monolayer of molecules is achieved when using SEIRA.Our work provides a new strategy possible to activate high-order modes for designing multiband MIRAs with both nanobridges and nanogaps for such MIR applications as multiband SEIRAs,IR detectors,and beam-shaping of quantum cascade lasers in the future. | En-Ming You Yiqin Chen Jun Yi Zhao-Dong Meng Qian Chen Song-Yuan Ding Huigao Duan Martin Moskovits Zhong-Qun Tian | 2021 | Opto-Electronic Advances2021，4，12： | 0 |
| 9 | Honeycomb-like MXene/NiFeP_(x)–NC with“continuous”single-crystal enabling high activity and robust durability in electrocatalytic oxygen evolution reactions显示文摘The development of low-cost,stable,and robust non-noble metal catalysts for water oxidation is a pivotal challenge for sustainable hydrogen production through electrocatalytic water splitting.Currently,such catalysts suffer from high overpotential and sluggish kinetics in oxygen evolution reactions(OERs).Herein,we report a“continuous”single-crystal honeycomb-like MXene/NiFeP_(x)–N-doped carbon(NC)heterostructure,in which ultrasmall NiFeP_(x)nanoparticles(NPs)encapsulated in the NC are tightly anchored on a layered MXene.Interestingly,this MXene/NiFeP_(x)–NC delivers outstanding OER catalytic performance,which stems from“continuous”single-crystal characteristics,abundant active sites derived from the ultrasmall NiFeP_(x)NPs,and the stable honeycomb-like heterostructure with an open structure.The experimental results are rationalized theoretically(by density functional theory(DFT)calculations),which suggests that it is the unique MXene/NiFeP_(x)–NC heterostructure that promotes the sluggish OER,thereby enabling superior durability and excellent activity with an ultralow overpotential of 240 mV at a current density of 10 mA×cm^(−2). | Xiaojun Zeng Yifei Ye Yongqing Wang Ronghai Yu Martin Moskovits Galen D.Stucky | 2023 | Journal of Advanced Ceramics2023，12，3： | 0 |
