Graphitic carbon nitride (g-C₃N₄) coupled with NiCoP nanoparticles with sizes around 5 nm have been fabricated via a controllable alcohothermal process. NiCoP is an excellent electron conductor and cocatalyst in photocatalytic reactions. The coupling between tiny NiCoP nanoparticles and g-C₃N₄ through in-situ fabrication strategy could be a promising way to eliminate the light screening effect, hinder the recombination of photo-induced charge carriers, and improve the charge transfer. The NiCoP/g-C₃N₄ nanohybrids exhibit an excellent photocatalytic activity in the hydrogen generation, with a significantly improved performance compared with original g-C₃N₄, CoP/g-C₃N₄ and Ni₂P/g-C₃N₄, respectively. This study paves a new way to design transition metal phosphides-based photocatalysts for hydrogen production.

已经通过可控的醇热工艺制备了与尺寸约为5 nm的NiCoP纳米颗粒偶联的石墨碳氮化物（gC ₃ N ₄）。NiCoP在光催化反应中是极好的电子导体和助催化剂。通过原位制备策略将微小的NiCoP纳米颗粒与gC ₃ N ₄偶联可能是消除光屏蔽效应，阻碍光诱导电荷载流子复合并改善电荷转移的一种有前途的方法。NiCoP / gC ₃ N ₄与原始gC ₃ N ₄，CoP / gC ₃ N ₄和Ni ₂ P / gC ₃ N ₄相比，纳米杂化物在制氢中表现出优异的光催化活性。这项研究为设计用于生产氢气的基于过渡金属磷化物的光催化剂开辟了一条新途径。
