Abstract
Solar energy is attracting much attention as an eco-friendly source for future energy needs. Herein, NiZnS photocatalysts were synthesized with a hydrothermal method at various sulfur contents. The ZnS material is widely used as a photocatalyst because of its high stability, low toxicity, and excellent charge separation characteristics. Nickel is..... More

Abstract
As interest in hydrogen energy grows, eco-friendly methods of producing hydrogen are being explored. CuBi₂O₄ is one of the p-type semiconductor cathode materials that can be used for photoelectrochemical hydrogen production via environment-friendly water electrolysis. CuBi₂O₄ has a bandgap of 1.5 – 1.8 eV which allows it to photogenerate electrons..... More

Abstract
Solar water splitting is an attractive method for producing hydrogen from renewable natural resources, and heterostructure photocatalysts have been widely investigated for photocatalytic applications. Hetero-component photocatalysts can reduce the charge recombination process by improving electron utilization, and are considered promising candidates for solar water splitting. Amongst various heterostructure systems, combinations..... More
