Abstract
The rational design and modification of heterojunction photocatalysts aimed at achieving fast charge transport and efficient photocatalytic performance is a central goal of solar-light-driven water splitting and hydrogen evolution, yet this remains a challenge. Herein, we prepare a hierarchical photocatalyst composed of a few-layer violet phosphorene (VP), cadmium sulfide (CdS) nanoparticles (NPs), and Pd single atoms (SAs) by a facile one-step ball-milling strategy. The underlying VP/CdS p–n heterojunctions are verified to adopt S-scheme directional charge transfer by combining in situ irradiated X-ray photoelectron spectroscopy and electron paramagnetic resonance. The atomically dispersed Pd sites of the…
