Visible-Light-Driven Valorization of Biomass Intermediates Integrated with H2 Production Catalyzed by Ultrathin Ni/CdS Nanosheets
TL;DR: Photocatalytic upgrading of crucial biomass-derived intermediate chemicals to value-added products (aldehydes and acids) was carried out on ultrathin CdS nanosheets decorated with nickel and led to complete transformation to the respective carboxylates with concomitant production of H2.
Journal ArticleDOI
Interfacing nickel nitride and nickel boosts both electrocatalytic hydrogen evolution and oxidation reactions.
TL;DR: In this paper, the authors report that interface engineering of Ni3N and Ni results in a unique Ni3Ni/Ni electrocatalyst which exhibits exceptional HER/HOR activities in aqueous electrolytes.
Journal ArticleDOI
Enhanced Electrocatalytic Hydrogen Oxidation on Ni/NiO/C Derived from a Nickel-Based Metal-Organic Framework.
Yang Yang,Xiaodong Sun,Guanqun Han,Xi Liu,Xiangyu Zhang,Yongfang Sun,Min Zhang,Zhi Cao,Yujie Sun +8 more
TL;DR: Ni/NiO/C exhibits an HOR activity one order of magnitude higher than that of its parent Ni/C counterpart measured under the same conditions and shows better stability and CO tolerance than commercial Pt/C in alkaline media which renders it a very promising HOR electrocatalyst for hydrogen fuel cell applications.
Journal ArticleDOI
Electrocatalytic and photocatalytic hydrogen evolution integrated with organic oxidation
Bo You,Guanqun Han,Yujie Sun +2 more
TL;DR: The importance of oxidative biomass valorization coupled with H2 production, as biomass is the only green carbon source whose scale is comparable to fossil fuels, is highlighted.
Journal ArticleDOI
Electrolyzer Design for Flexible Decoupled Water Splitting and Organic Upgrading with Electron Reservoirs
Wei Li,Nan Jiang,Bo Hu,Xuan Liu,Fuzhan Song,Guanqun Han,Taylor J. Jordan,Tanner B. Hanson,T. Leo Liu,Yujie Sun +9 more
TL;DR: In this paper, two inexpensive iron complexes as proton-independent electron reservoirs (ERs) are described for decoupled water electrolysis (Ferrocenylmethyl)trimethylammonium chloride and Na 4 [Fe(CN) 6 ], which have proper redox potentials in aqueous media, are able to couple their oxidation with HER.
