Plasma-Engineered CeO_x Nanosheet Array with Nitrogen-Doping and Porous Architecture for Efficient Electrocatalysis.

ABSTRACT: Surface engineering has been proved efficient and universally applicable in improving the performance of CeO₂ in various fields. However, previous approaches have typically required high-temperature calcination or tedious procedures, which makes discovery of a moderate and facile modification approach for CeO₂ an attractive subject. In this paper, porous CeO₂ nanosheets with effective nitrogen-doping were synthesized via a low-temperature NH₃/Ar plasma treatment and exhibited boosted hydrogen evolution reaction performance with low overpotential (65 mV) and long-term stability. The mechanism of the elevated performance was investigated by introducing Ar-plasma-treated CeO₂ with no nitrogen-doping as the control group, which revealed th
