Enhanced Stability and Charge Separation of InP by Assembling Al₂O₃ and Metallic Al for Photocatalytic Overall Water Splitting.

ABSTRACT: Photocatalytic hydrogen evolution from water is a sustainable approach to producing clean energy and promoting sustainable development. However, the low efficiency of photocatalysts under visible light and even near-infrared irradiation remains the current bottleneck in photocatalytic overall water splitting (POWS). Herein, we introduce an Al₂O₃/InP/Al photocatalyst with high efficiency and stability, which achieved an apparent quantum efficiency of 0.97% at 500 nm and operated for 10 h without significant performance decay. The high quantum efficiency and stability are attributed to the combination of the electron-rich Al reflective layer and Al₂O₃ protective layer coating, which synergistically facilitate charge separation. Additionally, the ne
