An efficient photocatalytic CO2 reduction has been reported in ZIF-67-derived-Co nanoparticles (NPs) encapsulated in nitrogen-doped carbon layers (N-C/Co). This work demonstrates that the pyrolysis temperature is crucial in tuning the grain size and components of metallic Co0 of N-C/Co composite catalysts, which optimizes their photocatalytic activities. Syntheses were conducted at 600, 700, and 800°C giving the N-C/Co-600, N-C/Co-700, and N-C/Co-800 samples, respectively. N-C layers can well wr...

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 employed as catalysts for photocatalytic CO2 reduct...
Photocatalytic syngas (CO and H2) production with CO2 as gas source not only ameliorates greenhouse effect, but also produces valuable chemical feedstocks. However, traditional photocatalytic system requires noble metal or suffers from low yield. Here, we demonstrate that S vacancies ZnIn2S4 (VS-ZnIn2S4) nanosheets are an ideal photocatalyst to drive CO2 reduction into syngas. It is found that building S vacancies can endow ZnIn2S4 with stronger photoabsorption, efficient electron-hole separatio...
