Ti3C2 assisting 1T&2H-MoS2/TiO2 Z-scheme heterojunction as a prospective photocatalyst for sulfamethazine degradation

Herein, we report a two-dimensional (2D) Ti3C2/1T&2H-MoS2/TiO2 photocatalyst obtained by in situ growth of a 1T&2H-MoS2/TiO2 Z-scheme heterojunction on a highly conductive Ti3C2 MXene surface. The spectral response range of the resulting Ti3C2/1T&2H-MoS2/TiO2 (Ti3C2:1T&2H-MoS2:TiO2= 1:10:10) photocatalyst was broadened and the band gap was reduced. These results demonstrate that Ti3C2 MXene assisted Z-type heterojunction is a feasible strategy to expand the optical absorption range and reduce the band gap of TiO2 for photocatalytic application.
