Current Progress of Metal Sulfides/Metal–Organic Frameworks Composite Materials for Photocatalytic H₂ Production

Researchers are exploring composite materials to address the challenges of conductivity and stability in metal–organic frameworks (MOFs), which have significant potential for photocatalysis, especially in light-driven water splitting for hydrogen production. Composites orientated toward metal sulfide/MOF synthesis for photocatalytic hydrogen triggered by observable light have garnered increasing attention recently. The emphasis is on metal sulfide/MOF composites, which provide effective charge separation, broad light absorption, and great photochemical stability. Although still in the early stages, these hybrid photocatalysts show promising real-world applications. The creation and formulation of several nanocomposites based on metal sulfide/MOFs regarding the photocatalytic H₂ production have advanced recently, and this article provides a thorough overview of these developments. The current review highlights recent advances in nanocomposites based on metal sulfide/MOFs, emphasizing their improved photocatalytic activity because of synergistic effects and the effective role of non-noble metal cocatalyst. It also highlights the existing challenges and outlines future research directions in the field of photocatalytic water splitting using metal sulfide/MOF nanocomposites.
