In this study, a novel Z-scheme heterojunction photocatalyst was developed by integrating g-C3N4 nanoplates into ZnIn2S4 microspheres. X-ray photoelectron spectroscopy analysis revealed directional electron transfer from to upon formation. Under irradiation, electrochemical tests and paramagnetic resonance demonstrated significantly enhanced charge generation separation efficiencies in the ZnIn2S4/g-C3N4 composite, accompanied reduced resistance. photocatalytic CO2 reduction, composite achieved highest CO yield, 1.92 5.83 times higher than those of pristine ZnIn2S4, respectively, with notable selectivity 91.3% compared H2 (8.7%). The mechanism, confirmed work, effectively preserved strong redox capabilities photoinduced carriers, leading superior performance excellent long-term stability. This study offers valuable insights design development g-C3N4-based heterojunctions for efficient solar-driven reduction.

Increasing the crystallinity of carbon nitride can accelerate photogenerated carrier migration rate and reduce structural defects, which is an effective strategy to improve photocatalytic performance nitride. In this work, microtubes were post-treated in KCl-LiCl molten salts create crystalline heptazinyl microtubes. The results show that hydrogen production as-prepared heptazine-based reach 3440.21 μmol·g–1·h–1, approximately 28.8, 2.1, 22.2 times higher than bulk nitride, sulfur doped g-C3N4 microtubes, with triazine-based structure prepared by a one-step salt method, respectively. method have structure, possessing not only high but also significantly increased specific surface area. This study offers reliable guide for designing innovative approach prepare semiconductor photocatalysts system.
