Current Progress of Metal Sulfides/Metal–Organic Frameworks Composite Materials for Photocatalytic H ₂ 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 H 2 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.
