Abstract Energy scarcity and environmental pollution have prompted research in hydrogen generation from solar to develop clean energy through highly efficient, effective, long-lasting photocatalytic systems. Designing a catalyst with robust stability an effective carrier separation rate was achieved heterostructure assembly, but certain functionalities must be explored. In this paper we designed ternary assembly of CdS nanospheres wrapped hierarchical shell walls layered MXene-tagged MoS 2 nanoflakes, forming intimate interfaces in-situ growth process. An in-layered wall MXene surface-wrapped nanoflakes as core–shell improved the photo-corrosion resistance accelerated production H (38.5 mmol g −1 h ), which is 10.7, 3.1, 1.9 times faster than that CdS, CdS–MXe, CdS–MoS nanostructures, respectively. The apparent quantum efficiency CdS–MXe 2.4 /MoS calculated 34.6% at λ = 420 nm. X-ray ultraviolet photoelectron spectroscopies validated electronic states, band alignment, work function heterostructures, whilst time-resolved photoluminescence measured lifespan evaluate charge migration CdS-MXe/MoS heterostructure. dual surface wrapping MXe/MoS over confirmed structural durability remained intact throughout reaction, promoting approximately 93.1% its catalytic property even after five repeatable cycles. This study examined how template improves opens new way design MXene-based durable catalysts for solar-energy conversion. Graphical
