Hierarchical Nanoassembly of MoS2/Co9S8/Ni3S2/Ni as a Highly Efficient Electrocatalyst for Overall Water Splitting in a Wide pH Range.
Yan Yang,Huiqin Yao,Zihuan Yu,Saiful Islam,Saiful Islam,Haiying He,Mengwei Yuan,Yonghai Yue,Kang Xu,Weichang Hao,Genban Sun,Huifeng Li,Shulan Ma,Shulan Ma,Peter Zapol,Mercouri G. Kanatzidis,Mercouri G. Kanatzidis +16 more
TL;DR: The results demonstrate that hierarchical metal sulfides can serve as highly efficient all-pH (pH = 0-14) electrocatalysts for overall water splitting.
Journal ArticleDOI
First-principles study of the structural, electronic, and optical properties of Ga 2 O 3 in its monoclinic and hexagonal phases
Haiying He,Roberto Orlando,M. A. Blanco,Ravindra Pandey,Emilie Amzallag,Isabelle Baraille,Michel Rérat +6 more
TL;DR: In this paper, the structural, electronic, and optical properties of Ga2O3 in its ambient, monoclinic and high-pressure, hexagonal phases in the framework of all-electron density functional theory were investigated.
Journal ArticleDOI
Dynamic stability of active sites in hydr(oxy)oxides for the oxygen evolution reaction
Dong Young Chung,Pietro P. Lopes,Pedro Farinazzo Bergamo Dias Martins,Haiying He,Tomoya Kawaguchi,Peter Zapol,Hoydoo You,Dusan Tripkovic,Dusan Strmcnik,Yisi Zhu,Soenke Seifert,Sungsik Lee,Vojislav R. Stamenkovic,Nenad M. Markovic +13 more
TL;DR: In this article, the authors show that the strong interaction of Fe with the MOxHy host is the key to controlling the average number of Fe active sites present at the solid/liquid interface.
Journal ArticleDOI
Role of Water and Carbonates in Photocatalytic Transformation of CO2 to CH4 on Titania
Nada M. Dimitrijevic,K. V. Baiju,Oleg G. Poluektov,Tijana Rajh,Kimberly A. Gray,Haiying He,Peter Zapol +6 more
TL;DR: Using the electron paramagnetic resonance technique, the multiple roles of water and carbonates in the overall photocatalytic reduction of carbon dioxide to methane over titania nanoparticles are elucidated.
Journal ArticleDOI
Highly selective electrocatalytic CO2 reduction to ethanol by metallic clusters dynamically formed from atomically dispersed copper
