Oxygen vacancies on Nb2O5 enhanced the performance of H2O2 electrosynthesis from O2 reduction

Abstract

A serial oxygen vacancy (OV) on Nb2O5 is synthesised by H2 calcination, and H-300 exhibited high selectivity and activity for H2O2 (93.4%, 562.5 mmol gcat−1). A volcano relationship is identified between the OV content and performance, which provides an attractive insight into designing electrocatalysts.
