Protein-Zn(II) networks derived N-doped porous carbon-supported ZnS for photothermally catalytic CO2 conversion. Issue 45 (March 2021) - Tang, Feiying
Graphical abstract: Highlights: N -doped porous carbon supported ZnS (ZnS/NPC) were prepared by pyrolysis of protein-Zn(II) networks. ZnS/NPC catalyst were obtained without introduction of extra templates and additional acid/base post-treatment. ZnS/NPC–2 possesses plenty of Lewis acid/base sites and high photothermally catalytic performance for CO2 conversion. Abstract: It is highly desired but remains challenging to develop efficient catalysts for CO2 conversion. Herein, N-doped porous carbon-supported ultra-small ZnS (ZnS/NPC‒X) were developed as photothermal catalysts for CO2 conversion by pyrolyzing the protein-Zn(II) network. The optimal catalyst ZnS/NPC‒2 possesses plenty of Lewis acid/base sites, hierarchical porous structure and high photothermal efficiency, jointly affording it high photothermally catalytic performance for CO2 cycloaddition and methylation reactions. This work provides a new strategy to prepare porous carbon-supported catalysts, which can find wide applications in photothermal catalysis.
