Abstract:
The objective of this practical study was to ascertain whether metal sulfides (Me= Ni, Cd, Bi, Mo) can demonstrate synergistic effects when combined with carbon nitride, particularly in the g-C3N4/Bi2S3 composite, for the photocatalytic production of hydrogen from water using sunlight [1]. This represents a significant advantage, as it circumvents the necessity for the use of costly co-catalysts such as platinum. In this study, the composite was created using a combination of thermal and mechanochemical synthesis. Samples with varying component ratios in terms of bismuth sulfide (33.3%, 5.25%, 2.56%, 1.27%, 0.5%) were prepared with the objective of identifying the most efficient photocatalyst for hydrogen production. The findings indicated that the most efficacious photocatalyst for hydrogen production was theg-C3N4/Bi2S3 ratio of 2.56%. The findings indicated that the combination of bismuth sulfide and carbon nitride in the presence of visible sunlight exhibited a synergistic effect, thereby enhancing photocatalytic efficiency. This has the effect of reducing the cost of utilizing the material in question as a photocatalyst and in synthesis. SEM images depicts of the bismuth sulfide as a tubular structure, while the carbonitride is represented as a layered composition. This work contributes to advancing the fields of photocatalysis, organic dye degradation, hydrogen generation, and materials science.
