Hydrogen evolution from water, catalyzed by solar energy, is a promising yet challenging endeavor. Small-sized catalysts usually exhibit high utilization and performance in the hydrogen field. However, surface energy tends to make them aggregate. In this study, we introduce novel molten salt synthesis technique develop composite catalyst featuring TiO2/C3N4 heterojunction stabilize small-sized TiO2. High-temperature salts create highly polarized environment that facilitates formation of smaller-sized Ti precursor, thereby enhancing integration with C3N4 structures significantly improving photocatalytic performance. Additionally, oxidation sacrificial reagents was examined using quasi-in-situ NMR technique, comprehensive discussion reaction products mechanisms. This research offers valuable insights for employing approach development photocatalysts other functional materials.

Abstract Poly (triazine imide) (PTI), a crystalline allotrope of polymeric carbon nitride, holds great promise for photocatalytic overall water splitting (OWS). However, previous results reveal that both H 2 and O evolution cocatalysts prefer to deposit on the prismatic facets, which in undesired backward reaction current unsatisfied quantum efficiency OWS reaction. Herein, situ decoration with heptazine based nitride (HCN) at interface PTI is successfully employed construct S‐scheme hetero‐phase junctions. The built‐in electric field HCN endows directed carrier separation, thereby enabling separation redox sites, as validated by theoretical experimental results. Accordingly, as‐synthesized PTI/HCN spatially separated charge carriers restrained achieves solar‐to‐hydrogen energy conversion 0.35%
