Triggering the electrocatalytic hydrogen evolution activity of the inert two-dimensional MoS2 surface via single-atom metal doping

16-Apr-2015 | Jiao Deng; Haobo Li; Jianping Xiao; Yunchuan Tu; Dehui Deng; Huaixin Yang; Huanfang Tian; Jianqi Li; Pengju Ren; Xin ..., Energy & Environmental Science, 2015

Electrocatalytic splitting of water is one of the most efficient technologies for hydrogen production, and two-dimensional (2D) MoS2 has been considered as a potential alternative to Pt-based catalysts in the hydrogen evolution reaction (HER). However, the catalytic activity of 2D MoS2 is always ...

Dopant-Controlled Selenization in Pd Nanocrystals: The Triggered Kirkendall Effect

10-Apr-2015 | Amit K. Guria; Gyanaranjan Prusty; Biplab K. Patra; Narayan Pradhan, Journal of the American Chemical Society, 2015

Doping foreign impurities in host nanomaterials can induce new materials properties. In addition, doping can also influence the crystallization process and change the shape and/or phase of the host material. While dopant-induced changes in the properties of materials have been well studied, the ...
