Herein, a series of porous nano‐structured carbocatalysts have been fused and decorated by Mo‐based composites, such as Mo₂C, MoN, and MoP, to form a hybrid structures. Using the open porosity derived from the pyrolysis of metal–organic frameworks (MOFs), the highly dispersive MoO₂ small nanoparticles can be deposited in porous carbon by chemical vapor deposition (CVD). Undergoing different treatments of carbonization, nitridation, and phosphorization, the Mo₂C‐, MoN‐, and MoP‐decorated carbocatalysts can be selectively prepared with un‐changed morphology. Among these Mo‐based composites, the MoP@Porous carbon (MoP@PC) composites exhibited remarkable catalytic activity for the hydrogen evolution reaction (HER) in 0.5 m H₂SO₄ aqueous solution versus MoO₂@PC, Mo₂C@PC, and MoN@PC. This study gives a promising family of multifunctional lab‐on‐a‐particle architectures which shed light on energy conversion and fuel‐cell catalysis.

UIO-66中受限磷化作用产生的多孔磷钼纳米八面体，可有效释放氢气

在此，一系列多孔的纳米结构碳催化剂已被Mo ₂ C，MoN和MoP等基于Mo的复合材料熔合和装饰，以形成杂化结构。利用金属-有机骨架（MOF）热解所产生的开孔率，可以通过化学气相沉积（CVD）将高度分散的MoO ₂小纳米颗粒沉积在多孔碳中。经历碳化，氮化和磷化的不同处理后，可以选择性地制备形态不变的Mo ₂ C-，MoN-和MoP装饰的碳催化剂。在这些基于Mo的复合材料中，MoP @多孔碳（MoP @ PC）复合材料在0.5 m H的氢分解反应（HER）中表现出显着的催化活性。 ₂ SO ₄水溶液相对于MoO ₂ @ PC，Mo ₂ C @ PC和MoN @ PC。这项研究提出了一个有希望的多功能实验室粒子体系结构系列，该体系结构阐明了能量转换和燃料电池催化作用。
