Photocatalytic water splitting for hydrogen (H₂) generation is a potential strategy to solve the problem of energy crisis and environmental deterioration. However, powder-like photocatalysts are difficult to recycle, and the agglomeration of particles would affect the photocatalytic activity. Herein, a direct Z-scheme CdS/WO₃ composite photocatalyst was fabricated based on carbon cloth through a two-step process. With the support of carbon cloth, photocatalysts tend to grow uniformly for further applications. The experimental results showed that the H₂ yield of adding one piece of CdS/WO3 composite material was 17.28 µmol/h, which was 5.5 times as compared to that of pure CdS-loaded carbon cloth material. A cycle experiment was conducted to verify the stability of the as-prepared material and the result demonstrated that the H₂ generation performance of CdS/WO₃ decreased slightly after 3 cycles. This work provides new ideas for the development of recyclable photocatalysts and has a positive significance for practical applications.

光催化分解水产生氢气 (H ₂ ) 是解决能源危机和环境恶化问题的潜在策略。然而，粉末状光催化剂难以回收利用，颗粒的团聚会影响光催化活性。在此，基于碳布，通过两步法制备了直接 Z 型 CdS/WO ₃复合光催化剂。在碳布的支撑下，光催化剂趋于均匀生长以供进一步应用。实验结果表明，加入1片CdS/WO 3的H ₂产率复合材料为 17.28 µmol/h，是纯负载 CdS 碳布材料的 5.5 倍。进行循环实验以验证所制备材料的稳定性，结果表明CdS/WO ₃的H ₂生成性能在3个循环后略有下降。该工作为可回收光催化剂的开发提供了新思路，对实际应用具有积极意义。
