摘要

Photocatalytic seawater splitting for H-2 production is extremely attractive in solar-to-fuel conversion areas toward achieving clean and renewable energy. In this study, we design a low-cost and robust Fe2O3/C-TiO2 Z-scheme system by applying Fe2O3 nanosheets as electron donor and C-doped TiO2 nanosheets as H-2 generation photocatalysts, achieving highly efficient seawater splitting for H-2 evolution without any sacrificial reagents. The Fe2O/C-TiO2 Z-scheme system shows remarkable catalytic performance and high stability for H-2 evolution in seawater. Under visible light illumination, the H-2 generation rate reach 170.8 mu mol g(-1) h(-1) and remain unchanged in a 24 h cyclic test. This study may open avenues to designing low-price and stable photocatalysts for H-2 extraction from seawater in future.
