Journal ArticleDOI
Uncovering near-free platinum single-atom dynamics during electrochemical hydrogen evolution reaction.
Shi Fang,Xiaorong Zhu,Xiaokang Liu,Jian Gu,Wei Liu,Danhao Wang,Wei Zhang,Yue Lin,Junling Lu,Shiqiang Wei,Yafei Li,Tao Yao +11 more
TL;DR: It is uncovered that the single Pt atom tends to dynamically release from the nitrogen-carbon substrate, with the geometric structure less coordinated to support and electronic property closer to zero valence, during the reaction.

Highly Active and Stable Single-Atom Cu Catalysts Supported by a Metal-Organic Framework
Ali M. Abdel-Mageed,Bunyarat Rungtaweevoranit,Bunyarat Rungtaweevoranit,Magdalena Parlinska-Wojtan,Xiaokun Pei,Xiaokun Pei,Omar M. Yaghi,Omar M. Yaghi,R. Jürgen Behm +8 more
TL;DR: Time-resolved operando spectroscopy measurements indicate that the activity of the catalyst is associated with atomically dispersed, positively charged ionic Cu species, which makes this interesting for application in catalytic converters for cars, and for CO removal via selective oxidation of CO in H2-rich feed gases, where it shows an excellent selectivity of about 100% for CO oxidation.
