As a significant technology of CO2 utilization, artificial CO2 photoreduction has received more and more attention. Herein, g-C3N4 catalysts modified with Bi and/or Cu for CO2 photothermal reduction were prepared by solvothermal synthesis and impregnation methods. Performance evaluation and physicochemical and photo- and thermochemical characterization indicated that Bi and Cu modification effectively enhanced the photo-absorption properties of g-C3N4 catalysts, improving charge transfer efficiency and catalytic performance. Compared with single-metal modification, Bi and Cu co-modification showed a narrower bandgap and more excellent light and CO2 absorption capacity, suggesting a certain synergistic effect of Bi and Cu co-modification. The alteration of the light absorption properties may be related to the surface plasmon effect of Bi and Cu, and the co-loading of Bi and Cu can exacerbate the effect, which can effectively enhance the photoresponsivity of the catalysts, leading to higher catalytic performance.

负载Bi、Cu的石墨氮化碳催化剂用于二氧化碳光热还原的研究
人工CO 2光还原作为CO 2利用的重要技术越来越受到人们的关注。本文通过溶剂热合成和浸渍方法制备了Bi和/或Cu修饰的用于CO 2光热还原的gC 3 N 4催化剂。性能评价以及物理化学和光热化学表征表明,Bi和Cu改性有效增强了gC 3 N 4催化剂的光吸收性能,提高了电荷转移效率和催化性能。与单金属修饰相比,Bi和Cu共修饰表现出更窄的带隙和更优异的光和CO 2吸收能力,表明Bi和Cu共修饰具有一定的协同效应。光吸收性能的改变可能与Bi和Cu的表面等离子体效应有关,Bi和Cu的共负载可以加剧这种效应,从而可以有效增强催化剂的光响应性,从而获得更高的催化性能。
