Photocatalytic water splitting is a promising route for clean energy production, yet remains constrained by poor carrier utilization and low solar-to-hydrogen (STH) efficiency.

Remarkably, can break traditional bandgap lower limits 1.23 eV, which enhances light absorption boosts STH efficiency 38.1% CrSSe 0 37% −2.5% CrSeTe range 7–11. This work highlights as powerful strategy enhance performance, offering insight designing high-efficiency photocatalysts.
