Abstract
An electrochemical N2 reduction reaction (NRR) that can be powered by electricity generated from renewable sources has recently gained heightened research interest, providing a promising alternative to the conventional Haber-Bosch process. Current major research efforts are being devoted to the design and development of advanced electrocatalysts to enhance the efficiency of NRR. Herein, guided by density functional theory calculations that predict the cooperative effect of Nb and anatase TiO2(110) in promoting electrocatalytic NRR performance, we successfully synthesize TiO2 single crystals with selectively exposed (110) facets, supplemented with Nb atomic loading, which exhibited remarkable performance for NRR, achieving an NH3 production rate of ∼21.3 μg h−1 mgcat−1 at −0.5 V (versus reversible hydrogen electrode).
