Highly Dispersive Ni@C and Co@C Nanoparticles Derived from Metal–Organic Monolayers for Enhanced Photocatalytic CO₂ Reduction

The metal/carbon composites prepared by direct pyrolysis of metal–organic frameworks (MOFs) are regarded as ideal catalysts. However, conventional MOFs show a three-dimensional bulk structure. For bulk MOF-derived catalysts, most active metal sites are confined in the interior and not fully utilized. In this work, metal–organic monolayers (MOLs) are used as the starting precursors to prepare carbon-wrapped metal nanoparticles, which are further...
