Ternary Ti 3 C 2 –OH/ln 2 S 3 /CdS composites with an efficient visible-light-driven photocatalytic performance have been prepared via a facile hydrothermal synthesis method. The photo-degradation experiments verified that Ti 3 C 2 –OH/ln 2 S 3 /CdS composite with a large surface area of 68.2 m2/g exhibited an enhanced photocatalytic activity and adsorption capacity towards Rhodamine B under visible light irradiation, which was higher than that of the naked CdS and ln 2 S 3 , respectively. Furthermore, Ti 3 C 2 –OH/ln 2 S 3 /CdS composite showed robust degradation efficiency for mixture dyes of RhB and Methyl Orange (MO), and its catalytic ability was superior to that of ternary GO/ln 2 S 3 /CdS composite. The trapping experiments for active species revealed that hole (h+) and •O 2 − species played a critical role in the removal of organic pollutants. In summary, the enhanced photocatalytic performance of Ti 3 C 2 –OH/ln 2 S 3 /CdS photocatalyst was derived from an excellent charge carrier separation and transfer of Ti 3 C 2 –OH MXene and the synergistic effect between CdS and ln 2 S 3 which resulting in strong visible light response.
