Autor: Yequan Xiao, Zeyu Fan, Mamiko Nakabayashi, Qiaoqiao Li, Liujiang Zhou, Qian Wang, Changli Li, Naoya Shibata, Kazunari Domen, Yanbo Li

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-10 (2022)

While photoelectrochemical water splitting offers a promising means to obtain renewable H2, it is challenging to balance light absorption and carrier transport in semiconductor thin films. Here, authors combine surface doping and bulk gradient doping

A self-healing catalyst for electrocatalytic and photoelectrochemical oxygen evolution in highly alkaline conditions

Autor: Chao Feng, Faze Wang, Zhi Liu, Mamiko Nakabayashi, Yequan Xiao, Qiugui Zeng, Jie Fu, Qianbao Wu, Chunhua Cui, Yifan Han, Naoya Shibata, Kazunari Domen, Ian D. Sharp, Yanbo Li

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-10 (2021)

While self-healing catalysts may survive the harsh environments used for oxygen evolution, understanding how to develop such electrocatalysts remains a challenge. Here, authors find cobalt to promote the self-healing of leached iron centers in borate

Heterojunction solar cells based on graphene woven fabrics and silicon

Autor: Yujia Zhong, Yequan Xiao, Qiao Chen, Hongwei Zhu

Publikováno v: Journal of Materiomics, Vol 4, Iss 2, Pp 135-138 (2018)

Graphene-on-semiconductor has been proved to be a quality heterojunction with efficient photoelectric conversion. In this work, we constructed Schottky junction solar cells by combing graphene woven fabrics (GWFs) and n-doped single crystal silicon,

Stable seawater oxidation with a self-healing oxygen-evolving catalyst

Autor: Xiaojian Zhang, Chao Feng, Zeyu Fan, Beibei Zhang, Yequan Xiao, Andraž Mavrič, Nadiia Pastukhova, Matjaz Valant, Yi-Fan Han, Yanbo Li

Publikováno v: Inorganic Chemistry Frontiers. 10:3103-3111

Stable seawater oxidation at a large current density of 500 mA cm−2 for 1000 h is achieved with a self-healing borate-intercalated nickel–cobalt–iron oxyhydroxide (NiCoFe-Bi) catalyst in highly alkaline artificial seawater at pH 14.95.
