Abstract The majority of visible light-active plasmonic catalysts are often limited to Au, Ag, Cu, Al, etc., which have considerations in terms costs, accessibility, and instability. Here, we show hydroxy-terminated nickel nitride (Ni 3 N) nanosheets as an alternative these metals. Ni N catalyze CO 2 hydrogenation with a high production rate (1212 mmol g −1 h ) selectivity (99%) using light. Reaction shows super-linear power law dependence on the light intensity, while quantum efficiencies increase intensity reaction temperature. transient absorption experiments reveal that hydroxyl groups number hot electrons available for photocatalysis. situ diffuse reflectance infrared Fourier transform spectroscopy proceeds via direct dissociation pathway. excellent photocatalytic performance (without co-catalysts or sacrificial agents) is suggestive use metal nitrides instead conventional nanoparticles.
