Boosting Charge Separation in a CdIn 2 S 4 /Mo 2 TiC 2 MXene Schottky Heterojunction for Enhanced Photocatalytic Hydrogen Production

ABSTRACT Mo 2 TiC 2 MXene was exfoliated in situ using hydrofluoric acid solution and subsequently integrated with CdIn 2 S 4 through physical stirring and grinding. The composite material demonstrated exceptional photocatalytic hydrogen evolution (PHE) activity without the loading of any noble metal co‐catalysts, achieving a hydrogen production rate as high as 3.35 mmol·h −1 g −1 . This represents a 55.83‐fold enhancement compared to pristine CdIn 2 S 4 and surpasses the performance of most reported CdIn 2 S 4 ‐based photocatalytic materials. Furthermore, the composite material maintained consistent hydrogen evolution performance throughout four consecutive cycling tests, demonstrating excellent cycling…
