Paving the way out of sustainable energy applications, one most captivating aspirations is development state-of-the-art catalytic systems for harnessing hydrogen energy. Here, a unique MoSe2–MoS2/ZnO heterojunction with S-scheme-type band alignment has been modeled to elucidate its ascendancy toward PC, EC, and PEC generation. Optimized 5 wt % (5MMZ) exhibited 5-fold superior PC H2 production efficiency than bare ZnO, 58.6% AQY ascribed augmented solar harvesting improved photophysical properties as confirmed by optoelectronic theoretical analysis. Femtosecond transient absorption studies were carried provide deeper insights into photoinduced charge carrier behavioral dynamics. It revealed that delayed recombination electron carriers at shallow deep trap sites holes was accountable higher activity 5MMZ heterostructure. XPS DFT ascertained great deal correlation between experimental achievements predictions discussed in reaction mechanism. To determine diversified scope heterojunctions green generation, photo/electrochemical water splitting operations also performed, which further reinforced versatility this kind metal oxide (ZnO)-bilayered material (MoSe2–MoS2)-type ternary heterostructures.
