Summary: In this study, C3N4-functionalized MoS2 nanoflowers were fabricated using a hydrothermal method and applied for the removal of organic pollutants from water. The heterojunction formation between MoS2 and C3N4 nanosheets was confirmed, and the as-prepared 2D C3N4-MoS2 nanohybrids exhibited significant photocatalytic performance. The highest heterojunction density of the nanohybrids showed enhanced photodecomposition performance due to effective charge separation.

Summary: This article introduces a method of improving the activity of MoS2 by transition metal (Ni) doping and exfoliation, enhancing its performance in hydrogen production photocatalytic reactions. The results of the study show that the modified MoS2/CdS composite has 70 times higher activity in hydrogen production compared to pure CdS, with stable hydrogen production ability. Metal doping and exfoliation improve the conductivity, surface area, and active sites of MoS2, while promoting catalytic kinetics and effective utilization of photogenerated charges.
