Theoretical insight into the relevance between the oxidation states of CeO₂ supported Pt^{4+/2+/1+/0/2−} and their HER performance

Abstract

The oxidation states(OSs) of Pt catalysts play a key role in their hydrogen evolution reaction(HER) reaction, which has become a focus in recent years. As for the Pt/CeO2 catalysts, we...

“…The electron transfer between the supports and electrocatalysts would regulate the electronic structures of electrocatalysts, further impacting their HER performances. 61,62 It is especially distinct that the electrons could inject to (or recover from) Ce-4f orbitals, acting as a particularly efficient electron buffer.
