| 1 | Porous LaFeO3 nanofiber with oxygen vacancies as an efficient electrocatalyst for N2 conversion to NH3 under ambient conditions显示文摘Electrocatalytic N2 reduction to NH3 under ambient conditions is an eco-friendly and sustainable alternative to the traditional Haber-Bosch process. However, inhibited by the high activation barrier of N2, this process needs efficient electrocatalysts to adsorb and activate the N2, enabling the N2 reduction reaction(NRR). Herein, we report that porous LaFeO3 nanofiber with oxygen vacancies acts as an efficient NRR electrocatalyst with abundant active sites to enhance the adsorption and activation of N2. When tested in 0.1 M HCl, such electrocatalyst achieves a high Faradaic efficiency of 8.77% and a large NH3 yield rate of 18.59 μg h–1 mgcat–1.at-0.55 V versus reversible hydrogen electrode. This catalyst also shows high long-term electrochemical stability and excellent selectivity for NH3 formation. Density functional theory calculations reveal that, by introducing oxygen vacancy on LaFeO3, the subsurface metallic ions are exposed with newly localized electronic states near the Fermi level, which facilitates the adsorption and activation of N2 molecules as well as the subsequent hydrogenation reactions. | Chengbo Li Dongwei Ma Shiyong Mou Yongsong Luo Benyuan Ma Siyu Lu Guanwei Cui Quan Li Qian Liu Xuping Sun | 2020 | Journal of Energy Chemistry2020，29，11： | 6 |
| 2 | Benzoate anions-intercalated NiFe-layered double hydroxide nanosheet array with enhanced stability for electrochemical seawater oxidation显示文摘Seawater electrolysis is an extremely attractive approach for harvesting clean hydrogen energy,but detrimental chlorine species(i.e.,chloride and hypochlorite)cause severe corrosion at the anode.Here,we report our recent finding that benzoate anions-intercalated NiFe-layered double hydroxide nanosheet on carbon cloth(BZ-NiFe-LDH/CC)behaves as a highly efficient and durable monolithic catalyst for alkaline seawater oxidation,affords enlarged interlayer spacing of LDH,inhibits chlorine(electro)chemistry,and alleviates local pH drop of the electrode.It only needs an overpotential of 320 mV to reach a current density of 500 mA·cm^(−2)in 1 M KOH.In contrast to the fast activity decay of NiFe-LDH/CC counterpart during long-term electrolysis,BZ-NiFe-LDH/CC achieves stable 100-h electrolysis at an industrial-level current density of 500 mA·cm^(−2)in alkaline seawater.Operando Raman spectroscopy studies further identify structural changes of disorderedδ(NiIII-O)during the seawater oxidation process. | Longcheng Zhang Jie Liang Luchao Yue Kai Dong Jun Li Donglin Zhao Zerong Li Shengjun Sun Yongsong Luo Qian Liu Guanwei Cui Abdulmohsen Ali Alshehri Xiaodong Guo Xuping Sun | 2022 | Nano Research Energy2022，1，3： | 6 |
| 3 | Ni(OH)_(2) nanoparticles encapsulated in conductive nanowire array for high-performance alkaline seawater oxidation显示文摘Design and development of high-efficiency and durable oxygen evolution reaction(OER)electrocatalysts is crucial for hydrogen production from seawater splitting.Herein,we report the in situ electrochemical conversion of a nanoarray of Ni(TCNQ)2(TCNQ=tetracyanoquinodimethane)on graphite paper into Ni(OH)_(2) nanoparticles confined in a conductive TCNQ nanoarray(Ni(OH)_(2)-TCNQ/GP)by anode oxidation.The Ni(OH)_(2)-TCNQ/GP exhibits high OER performance and demands overpotentials of 340 and 382 mV to deliver 100 mA·cm^(−2) in alkaline freshwater and alkaline seawater,respectively.Meanwhile,the Ni(OH)_(2)-TCNQ/GP also demonstrates steady long-term electrochemical durability for at least 80 h under alkaline seawater. | Longcheng Zhang Jiaqian Wang Pengyu Liu Jie Liang Yongsong Luo Guanwei Cui Bo Tang Qian Liu Xuedong Yan Haigang Hao Meiling Liu Rui Gao Xuping Sun | 2022 | Nano Research2022，15，7： | 5 |
| 4 | N-doped carbon nanotubes supported CoSe_(2) nanoparticles:A highly efficient and stable catalyst for H_(2)O_(2) electrosynthesis in acidic media显示文摘Electrocatalytic oxygen reduction reaction(ORR)provides an attractive alternative to anthraquinone process for H_(2)O_(2) synthesis.Rational design of earth-abundant electrocatalysts for H_(2)O_(2) synthesis via a two-electron ORR process in acids is attractive but still:very challenging.In this work,we report that nitrogen-doped carbon nanotubes as a multi-functional support for CoSe2 nanoparticles not only keep CoSe_(2) nanoparticles well dispersed but alter the crystal structure,which in turn improves the overall catalYtic behaviors and thereby renders high O_(2)-to-H_(2)O_(2) conversion efficiency.In 0.1 M HClO_(4),such CoSe_(2)@NCNTs hybrid delivers a high H_(2)O_(2) selectivity of 93.2% and a large H_(2)0_(2) yield rate of 172 ppm·h^(-1) with excellent durability up to 24 h.Moreover,CoSe_(2)@NCNTs performs effectively for organic dye degradation via electro-Fenton process. | Longcheng Zhang Jie Liang Luchao Yue Zhaoquan Xu Kai Dong Qian Liu Yonglan Luo Tingshuai Li Xiaohong Cheng Guanwei Cui Bo Tang Abdulmohsen Ali Alshehri Khalid Ahmed Alzahrani Xiaodong Guo Xuping Sun | 2022 | Nano Research2022，15，1： | 2 |

| 6 | “Ferrero-like”nanoparticles knotted injectable hydrogels to initially scavenge ROS and lastingly promote vascularization in infarcted hearts显示文摘Myocardial infarction(MI)exhibits a complicated and ever-accelerated pathological change involving excessive reactive oxygen species(ROS)and the up-regulation of pro-inflammatory cytokines in the initial stage,and a permanently inadequate blood supply.Herein,an injectable hydrogel fabricated by nanoparticles(NPs)knotted thiolated hyaluronic acid(HA-SH)was reported to reverse the hostile microenvironment and rebuild the heart functions after MI.Inspired by the composite shell-core structure of Ferrero chocolate sphere,a mimetic nanocarrier was designed to consist of the hydrophobic dimethyloxalylglycine(DMOG)NPs core and a thick polydopamine(PDA)shell formed by the self-polymerization of dopamine embedded with watersoluble drug epigallocatechin-3-gallate(EGCG)throughπ-πinteractions.The resulted'Ferrero-like'NPs exhibited a'three-inone'capacity,namely loading two distinct drugs,elimination of ROS,and serving a crosslinker to knot HA-SH.'Ferrero-like'NPs and HA-SH could rapidly form a hydrogel that exhibited a stable mechanical property,high capability to capture ROS,and programmed release of EGCG and DMOG.Four weeks after deploying the'Ferrero-like'NPs knotted hydrogels into rat infarcted hearts,the ejection fraction(EF)increased by 23.7%,and the infarct size decreased by 21.1%,and the fibrotic area reduced by 24.4%.The outcomes of immunofluorescence staining and reverse transcription-polymerase chain reaction(RTPCR)demonstrated a down-regulation of inflammatory factors(tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),interferon-γ(IFN-γ)),up-regulation of vascular related growth factors(hypoxia inducible factor-1α(HIF-1α),vascular endothelial growth factor A(VEGFA),von Willebrand factor(vWF),angiopoietin-1(Ang-1))and cardiac-related m RNAs(gap junction protein(Cx43),Cadherin 2).All in all,in this report,a very simple approach to intertemporally address the intricate and ongoing pathological changes after MI by injecting'Ferrero-like'NPs knotted hydrogels is developed to reverse hostile microenvironment,with an ability to scavenge ROS,down-regulate pro-inflammation factors in the first stage,and promote angiogenesis in a long term,thereby contributing to a significant improvement of heart functions. | HAN XiaoXu LI Lan XIE Tian CHEN Si ZOU Yang JIN Xin LI Sheng WANG Meng HAN Ning FAN GuanWei LIU WenGuang WANG Wei | 2020 | Science China(Technological Sciences)2020，63，11： | 2 |

| 11 | SUMO1 regulates post-infarct cardiac repair based on cellular heterogeneity显示文摘Small ubiquitin-related modifier(SUMOylation)is a dynamic post-translational modification that maintains cardiac function and can protect against a hypertrophic response to cardiac pressure overload.However,the function of SUMOylation after myocardial infarction(MI)and the molecular details of heart cell responses to SUMO1 deficiency have not been determined.In this study,we demonstrated that SUMO1 protein was inconsistently abundant in different cell types and heart regions after MI.However,SUMO1 knockout significantly exacerbated systolic dysfunction and infarct size after myocardial injury.Single-nucleus RNA sequencing revealed the differential role of SUMO1 in regulating heart cells.Among cardiomyocytes,SUMO1 deletion increased the Nppa^(+)Nppb^(+)Ankrd1^(+)cardiomyocyte subcluster pro-portion after MI.In addition,the conversion of fibroblasts to myofibroblasts subclusters was inhibited in SUMO1 knockout mice.Importantly,SUMO1 loss promoted proliferation of endothelial cell subsets with the ability to reconstitute neovascularization and expressed angiogenesis-related genes.Computational analysis of ligand/receptor interactions suggested putative pathways that mediate cardiomyocytes to endothelial cell communication in the myocardium.Mice preinjected with cardiomyocyte-specific AAV-SUMO1,but not the endothelial cell-specific form,and exhibited ameliorated cardiac remodeling following MI.Collectively,our results identified the role of SUMO1 in cardiomyocytes,fibroblasts,and endothelial cells after MI.These findings provide new insights into SUMO1 involvement in the patho-genesis of MI and reveal novel therapeutic targets. | Zhihao Liu Xiaozhi Liu Li Liu Ying Wang Jie Zheng Lan Li Sheng Li Han Zhang Jingyu Ni Chuanrui Ma Xiumei Gao Xiyun Bian Guanwei Fan | 2023 | Journal of Pharmaceutical Analysis2023，13，2： | 0 |
