CO2 Reduction: Oxygen Doping Induced by Nitrogen Vacancies in Nb4N5 Enables Highly Selective CO2 Reduction (Small 2/2020)

In article number 1905825, Yuan Qiu, Xijun Liu, and co-workers design a simple yet novel strategy to develop oxygen-doped Nb4N5 by introducing nitrogen-vacancy. The catalyst exhibits efficient performance for selective conversion of CO2 to CO and simultaneous excellent durability. The work provides a new perspective for an in-depth understanding toward the structure–activity relationship between defects and electrocatalysis.
