To enhance the photocatalytic activity, loading proper semiconductor with high efficiency and low cost is one of the most valid approaches. Herein, various amounts of CoWO₄ as a novel metal-free material were loaded on Mn_0.47Cd_0.53S (MCS) nanorods for photocatalytic hydrogen production reaction. The CoWO₄/Mn_0.47Cd_0.53S-25 (CW/MCS-25) exhibits the highest hydrogen production rate of 41.53 mmol·h⁻¹·g⁻¹ in the Na₂S/Na₂SO₃ system, which is about 2.68 times higher than that of pristine MCS. The Mapping and HRTEM reveals the deposited of CoWO₄ on the MCS. The detailed analyses of XPS, EIS, TRPL spectra and transient photocurrent responses indicate that CoWO₄ and MCS interacted closely and the photogenerated electrons of CoWO₄ can be transferred into MCS. In particular, the introduction of CoWO₄ can further transfer the photogenerated holes of MCS, thereby inhibiting the photocorrosion of MCS and improving photocatalytic activity. This work provides a reference for the exploration of noble metal-free composite material and shows great potential in the photocatalytic application.

为了提高光催化活性，高效、低成本地负载合适的半导体是最有效的方法之一。在此，不同量的CoWO ₄作为一种新型无金属材料负载在Mn _0.47 Cd _0.53 S (MCS) 纳米棒上用于光催化制氢反应。CoWO ₄ /Mn _0.47 Cd _0.53 S-25 (CW/MCS-25)在Na ₂ S/Na ₂ SO ₃体系中的产氢率最高，为41.53 mmol·h ^-1 ·g ^-1，约为比原始 MCS 高 2.68 倍。映射和 HRTEM 揭示了 CoWO _4的沉积在 MCS 上。XPS、EIS、TRPL光谱和瞬态光电流响应的详细分析表明，CoWO ₄和MCS相互作用密切，CoWO ₄的光生电子可以转移到MCS中。特别是CoWO ₄的引入可以进一步转移MCS的光生空穴，从而抑制MCS的光腐蚀，提高光催化活性。该工作为无贵金属复合材料的探索提供了参考，在光催化应用中显示出巨大的潜力。
