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.

高度期望但对于开发用于CO ₂转化的有效催化剂仍然具有挑战性。在此，通过热解蛋白质-Zn（II）网络，开发了N掺杂的多孔碳负载超小型ZnS（ZnS / NPC‒X）作为CO ₂转化的光热催化剂。最佳的催化剂ZnS / NPC‒2具有大量的路易斯酸/碱位，分层的多孔结构和较高的光热效率，共同为CO ₂环加成和甲基化反应提供了较高的光热催化性能。这项工作提供了一种制备多孔碳负载催化剂的新策略，该催化剂可以在光热催化中找到广泛的应用。
