Abstract

Photocatalytic reduction of CO2 is considered as a kind of promising technologies for solving the greenhouse effect. Herein, a novel hybrid structure of g-C3N4/ZnO/Ti3C2 photocatalysts was designed and fabricated to investigate their abilities for CO2 reduction. As demonstration, heterojunction of g-C3N4/ZnO can improve photogenerated carriers’ separation, the addition of Ti3C2 fragments can further facilitate the photocatalytic performance from CO2 to CO. Hence, g-C3N4/ZnO/Ti3C2 has efficiently increased CO production by 8 and 12 times than pristine g-C3N4 and ZnO, respectively. Which is ascribed to the photogenerated charge migration promoted by metallic Ti3C2. This work provides a guideline for designing efficient hybrid catalysts on other applications in the renewable energy fields.

MXene Ti3C2修饰的g-C3N4/ZnO光催化剂具有改善的光催化CO2还原性能
光催化还原CO2被认为是解决温室效应的一种很有前途的技术。本文设计并制备了一种新型的g-C3N4/ZnO/Ti3C2光催化剂杂化结构,以研究其还原CO2的能力。作为证明,g-C3N4/ZnO的异质结可以改善光生载流子的分离,Ti3C2片段的添加可以进一步促进从CO2到CO的光催化性能。因此,g-C3N1/ZnO/Ti3C2分别比原始g-C3N4和ZnO有效地增加了8倍和12倍的CO产量。这归因于金属Ti3C2促进的光生电荷迁移。这项工作为在可再生能源领域的其他应用中设计高效的混合催化剂提供了指导。
