Two-dimensional g-C3N4: an ideal platform for examining facet selectivity of metal co-catalysts in photocatalysis

Abstract

Two-dimensional g-C₃N₄ nanosheets with few-layer thickness, ensuring equivalent charge migrations to various Pd facets, provide an ideal model system for reliably examining the facet selectivity of Pd co-catalysts. It reveals that reduction of CO₂ can occur better on Pd{111} facets while H₂O prefers to generate H₂ on Pd{100}.
