Journal ArticleDOI
Chemical and structural origin of lattice oxygen oxidation in Co–Zn oxyhydroxide oxygen evolution electrocatalysts
Zhen-Feng Huang,Jiajia Song,Yonghua Du,Shibo Xi,Shuo Dou,Jean Marie Vianney Nsanzimana,Cheng Wang,Zhichuan J. Xu,Xin Wang +8 more
TL;DR: In this paper, the authors investigated Co-Zn oxyhydroxide electrocatalysts, and suggested that the mechanism depends on the amount of Zn2+ they contain, and found that Zn0.2Co0.8 has the optimum activity.
Journal ArticleDOI
High phase-purity 1T′-MoS 2 - and 1T′-MoSe 2 -layered crystals
Yifu Yu,Yifu Yu,Gwang-Hyeon Nam,Qiyuan He,Xue-Jun Wu,Kang Zhang,Zhenzhong Yang,Junze Chen,Qinglang Ma,Meiting Zhao,Zhengqing Liu,Feirong Ran,Xingzhi Wang,Hai Li,Xiao Huang,Bing Li,Qihua Xiong,Qing Zhang,Zheng Liu,Lin Gu,Yonghua Du,Wei Huang,Wei Huang,Wei Huang,Hua Zhang +24 more
TL;DR: It is shown that micrometre-sized metallic 1T′-MoS2- and 1T-MoSe2-layered crystals can be prepared in high phase purity on a large scale, and that they display promising electrocatalytic activity towards the hydrogen evolution reaction.
Journal ArticleDOI
In Situ Raman Spectroscopy of Copper and Copper Oxide Surfaces during Electrochemical Oxygen Evolution Reaction: Identification of CuIII Oxides as Catalytically Active Species
TL;DR: In this paper, X-ray diffraction, cyclic voltammetry, chronoamperometry, and in situ Raman spectroscopy were used to investigate the electrochemical oxygen evolution reaction (OER) on Cu, Cu2O, Cu(OH)2, and CuO catalysts.
Journal ArticleDOI
Iron-facilitated dynamic active-site generation on spinel CoAl2O4 with self-termination of surface reconstruction for water oxidation
Tianze Wu,Shengnan Sun,Jiajia Song,Shibo Xi,Yonghua Du,Bo Chen,W. A. Sasangka,Hanbin Liao,Chee Lip Gan,Chee Lip Gan,Günther G. Scherer,Lin Zeng,Haijiang Wang,Hui Li,Alexis Grimaud,Zhichuan J. Xu +15 more
TL;DR: In this article, a strategy using Fe substitution was proposed to enable the inactive spinel CoAl2O4 to become highly active and superior to the benchmark IrO2. But, it was not shown that the Fe substitution can facilitate surface reconstruction into active Co oxyhydroxides under OER conditions.
