Semimetallic Bismuthene with Edge‐Rich Dangling Bonds: Broad‐Spectrum‐Driven and Edge‐Confined Electron Enhancement Boosting CO2 Hydrogenation Reduction

Broad-spectrum-driven high-performance artificial photosynthesis is quite challenging. Herein, atomically ultrathin bismuthene with semimetallic properties is designed and demonstrated for broad-spectrum (ultraviolet-visible-near infrared light) (UV-vis-NIR)-driven photocatalytic CO
