In a recent article, researchers presented an iridium single-atom catalyst coordinated with cobalt–iron hydroxides, showing enhanced performance for oxygen evolution reactions (OER). This ...

The iridium is not the same as the iron it replaces, so the crystal structure is a bit distorted at those points. Structure could still play a role, but these sorts of defects usually have to be ...

By examining Figs 3a,b and 2c,d, we propose the following changes in the positions of the atoms in these two consecutive frames: the iridium atom in column 10 hops to column 3, the rhodium atom in ...

A new way of anchoring individual iridium atoms to the surface of a catalyst increased its efficiency in splitting water molecules to record levels, scientists from the Department of Energy’s ...

The enhanced performance was attributed to the distinct electronic structure resulting from iridium single-atom coordination with cobalt–iron hydroxides. Atomic force microscopy (AFM) revealed a ...

Sep 01, 2021: A new approach creates an exceptional single-atom catalyst for water splitting (Nanowerk News) A new way of anchoring individual iridium atoms to the surface of a catalyst increased its ...
