Novel noble-metal-free Ni₁₂P₅/CdS composite was designed and synthesized by a hydrothermal method. The photocatalytic H₂ generation activity of the as-prepared Ni₁₂P₅/CdS is 1.93 fold of that of pure CdS under visible light (λ > 420 nm) irradiation. The enhanced activity of Ni₁₂P₅/CdS is ascribed to the improved separation efficiency of photocarriers over a direct Z-scheme mechanism. It provides a potential strategy to improve the photocatalytic H₂ evolution activity of CdS greatly by loading noble-metal-free Ni₁₂P₅ as electron co-catalyst via direct Z-scheme mechanism.

新型无贵金属Ni ₁₂ P ₅ / CdS复合材料的优异可见光光催化H ₂析出活性

通过水热法设计合成了新型无贵金属Ni ₁₂ P ₅ / CdS复合材料。制备的Ni ₁₂ P ₅ / CdS在可见光（λ> 420 nm）照射下的光催化H ₂生成活性是纯CdS的1.93倍。Ni ₁₂ P ₅ / CdS活性的提高归因于通过直接Z方案机理提高了光载体的分离效率。通过直接加入无贵金属的Ni ₁₂ P ₅作为电子助催化剂，可以为提高CdS的光催化H ₂析出活性提供潜在的策略。Z方案机制。
