Abstract

• Mesoporous g-C 3 N 4 /Ti 3 C 2 T x (MCT) was prepared. • MCT showed highly photocatalytic activity for CO 2 reduction. • The photocatalytic mechanism was researched. Photocatalytic CO 2 reduction reactions (CO 2 RRs) are of significant interest for its application prospects in energy field and CO 2 removal in air. Herein we report mesoporous g-C 3 N 4 /Ti 3 C 2 T x (MCT) as a highly active photocatalyst in CO 2 reduction reactions. We have found that mesoporous structures are compatible with high speed electronic transmission systems and demonstrate that MCT enables the excellent separation of electrons and holes. Mesoporous g-C 3 N 4 /Ti 3 C 2 T x (MCT) shows a production of CH 4 (2.117 μ m o l · g - 1 · h - 1 ), which is 2.4 times than that of mesoporous g-C 3 N 4 (MC). Large contact area of the catalyst has numerous adsorption sites for CO 2 as a result of the catalysts’ mesoporous structures. The MCT catalyst also possess an efficient separation of the charge carriers due to the high speed electronic transmission system of MXene.
