Synergistic optimization of triple phase junctions and oxygen vacancies over MnxCd1−xS/Ov-WO3 for boosting photocatalytic hydrogen evolution

The t-Mn 0.5 Cd 0.5 S/Ov-WO 3 (t-MCSW) composite exhibits an optimal activity (194. 2 mmol g −1 h −1 ), which is attributed to the synergistic effect of triple phase junctions connected by homojunctions, heterojunctions and oxygen vacancies.
