Abstract

For renewable energy, it is crucial to create effective photocatalysts with enhanced photo charge separation and transfer to produce photocatalytic hydrogen (H 2 ) efficiently utilizing light energy. Due to their distinct qualities and features, carbonaceous materials have so far been shown to be high-performance co-catalysts to substitute some conventionally costly metal materials in photocatalytic water splitting. Here, a novel ternary nanocomposite, simple hydrothermal process ball milling assisted and wet impregnation approach, a promising ternary nanocomposite is created as an efficient solar light driven photocatalyst. Utilizing a variety of analytical techniques, 3 % Cu 3 P/ZnS/g-C 3 N 4 nanocomposites as catalysts were characterized in order to check the hydrogen production and investigate their structural properties. The hydrogen production capability of the catalyst is studied by irradiating Na 2 SO 3 + Na 2 S solutes using a halogen bulb (250 W). The results demonstrated that in terms of photocatalytic activity towards H 2 production, 3 % Cu 3 P/ZnS/g-C 3 N 4 catalyst performed better than 3 % Cu 3 P/ZnS, Cu 3 P, ZnS, and g-C 3 N 4 . A composite containing 7.5 wt% g-C 3 N 4 demonstrated exceptional durability during photocatalytic hydrogen production, resulting in a 23,086 mol h -1 g 1 rate. Higher stability in electron-hole pairs created a higher absorption level of solar light could be responsible for this remarkable performance.
