Photocatalytic decomposition of water to hydrogen is an attractive way to simultaneously handle the energy crisis and environmental pollution issues. Herein, non-noble CoP is prepared facilely by phosphating an MOF precursor and used as a cocatalyst in photocatalytic hydrogen production. It significantly improved the photocatalytic activity through the accelerated separation of photoinduced charge carriers and the introduction of hydrogen formation sites. The optimal hydrogen production rate of CoP/TiO₂ composites is achieved at 1701.1 μmol·g^–1·h^–1, which is 72 times that of the pure TiO₂. Importantly, MOF derivatives have specific surface area, high crystallinity, etc., manifesting the unique potential for constructing versatile and effective cocatalysts. This work has a certain reference significance for developing efficient catalysts toward better photocatalysis.

MOF 衍生的非贵金属 CoP 纳米粒子改性 TiO2 用于增强光催化制氢

将水光催化分解为氢气是同时解决能源危机和环境污染问题的一种有吸引力的方法。在此，通过磷酸化 MOF 前体轻松制备非贵金属 CoP，并将其用作光催化制氢中的助催化剂。它通过加速光生载流子的分离和氢形成位点的引入显着提高了光催化活性。_{CoP/TiO 2}复合材料的最佳产氢速率为1701.1 μmol·g ^–1 ·h ^–1，是纯TiO _2的72倍. 重要的是，MOF衍生物具有比表面积、高结晶度等特点，显示出构建多功能高效助催化剂的独特潜力。该工作对于开发高效催化剂以实现更好的光催化具有一定的参考意义。
