Integration of a metallic interstitial co-catalyst (Ni3Mo3N) onto CdS nanorods accelerated charge separation and efficient photocatalytic hydrogen evolution

Abstract

A metallic interstitial compound Ni₃Mo₃N was synthesized as a co-catalyst modified CdS nanorod for the first time. Photocatalytic studies show that the efficient charge separation and transfer from CdS to Ni₃Mo₃N enables high visible-light-driven hydrogen evolution at 6.56 mmol g⁻¹ h⁻¹. The Schottky heterojunction between CdS and Ni₃Mo₃N might be the key factor for the high photocatalytic activity.
