| 1 | Methanol electro-oxidation to formate on iron-substituted lanthanum cobaltite perovskite oxides显示文摘Electrochemically producing formate by oxidizing methanol is a promising way to add value to methanol.Noble metal-based electrocatalysts,which have been extensively studied for the methanol oxidation reaction,can catalyze the complete oxidation of methanol to carbon dioxide,but not the mild oxidation to formate.As a result,exploring efficient and earth-abundant electrocatalysts for formate production from methanol is of interest.Herein,we present the electro-oxidation of methanol to formate,catalyzed by iron-substituted lanthanum cobaltite(LaCo_(1-x)Fe_(x)O_(3)).The Fe/Co ratio in the oxides greatly influences the activity and selectivity.This effect is attributed to the higher affinity of Fe and Co to the two reactants:CH3OH and OH,respectively.Because a balance between these affinities is favored,LaCo_(0.5)Fe_(0.5)O_(3) shows the highest formate production rate,at 24.5 mmol h^(-1) g_(oxide)^(-1),and a relatively high Faradaic efficiency of 44.4%in a series of(LaCo_(1-x)Fe_(x)O_(3))samples(x=0.00,0.25,0.50,0.75,1.00)at 1.6 V versus a reversible hydrogen electrode. | Fanxu Meng Chencheng Dai Zheng Liu Songzhu Luo Jingjie Ge Yan Duan Gao Chen Chao Wei Riccardo Ruixi Chen Jiarui Wang Daniel Mandler Zhichuan J.Xu | 2022 | eScience2022，2，1： | 1 |
| 2 | Palladium-Catalyzed Long-Range Isomerization of Aryl Olefins显示文摘Long-range olefin isomerization could lead to the remote functionalization of hydrocarbon chains,which is advantageous with regards to atom-,step-,and redox economy.However,present methodologies for long-range olefin isomerization are mainly focused on heteroatom directed remote olefin migration;studies using aryl groups as the directing group are limited.The limited examples either utilize aryl olefins with special substituted groups on a benzene ring,or use elaborately optimized ligands or co-catalysts to accelerate the isomerization.A more simple catalytic system for general aryl olefins,without the need for special ligands or co-catalysts,was to be developed.Herein,we report a Pd-catalyzed long-range olefin isomerization(up to 15 units)for general aryl olefins via a 1,2-hydrogen shift mechanism.This methodology provides a simple pathway to long-range olefin isomerization without the participation of special ligands or co-catalysts. | Qianyi Ge Jingjie Meng Huikang Liu Zehua Yang Zhengxing Wu Wanbin Zhang | 2022 | Chinese Journal of Chemistry2022，40，19： | 0 |
| 3 | Multidimensional defects tailoring local electron and Mg^(2+) diffusion channels for boosting magnesium storage performance of WO_(3)/MoO_(2)显示文摘Defect engineering presents great promise in addressing lower specific capacity,sluggish diffusion kinetics and poor cycling life issues in energy storage devices.Herein,multidimensional(0D/2D/3D) structural defects are constructed in WO_(3)/MoO_(2) simultaneously via competing for and sharing with O atoms during simple hydrothermal process.OD and 2D defects tailor local electron,activating more sites and generating built-in electric fields to yield ion reservoir,meanwhile,3D defect owning lower anisotropic property tailors Mg^(2+) diffusion channels to fully exploit Mg^(2+) adsorbed sites induced by OD and 2D defects,enhance the kinetics and maintain structural stability.Benefitted from synergistic effect of 0D/2D/3D structural defects,the designed WO_(3)/MoO_(2) shows the higher specific capacity(112.8 mA h g^(-1) at 50 mA g^(-1) with average attenuation rate per cycle of 0.068%),superior rate capability and excellent cycling stability(specific capacity retention of 80% after 1500 cycles at 1000 mA g^(-1)).This strategy provides design ideas of introducing multidimensional structural defects for tailoring local electron and microstructure to improve energy storage property. | Shiqi Ding Yuxin Tian Jiankang Chen He Lv Amin Wang Jingjie Dai Xin Dai Lei Wang Guicun Li Alan Meng Zhenjiang Li | 2023 | Journal of Energy Chemistry2023，，9： | 0 |
