In this paper, we report a two-step of hydrothermal and pyrolysis method for constructing S-Scheme heterojunction photocatalytic composite material with core-shell structure transformed from type-I heterojunction, SiO2@Cu2GaBO5@TiO2 (SCGBT), by combining bimetallic borate Cu2GaBO5 TiO2 as catalysts SiO2 dispersant. The Cu ions serve an electron transfer bridge hole oxidation active center, thereby promoting the spatial separation photogenerated charges to improve hydrogen production formaldehyde selectivity. Under simulated sunlight, rate SCGBT-550 (1524 μmol·g-1·h-1) was 1.8, 520, 1.7, 508, 1.3 7 times that T, CGB, ST, SCGB, h-CGBT, CGBT, respectively. And after 5 h, methanol reached 1511 μmol·g-1·h-1, which 2, 1500, 1.2, 3 selectivity up 99%. promising performance can be attributed dispersion provided SiO2, broadened light absorption range Cu2GaBO5, dual role ions. There are also interaction internal electric fields band bending guides electrons in conduction recombine holes valence band, promote migration outer-layer reduction reaction, while enhancing efficiency inner-layer reaction. reactions both occurs on surface catalyst, significantly improving electron-hole pairs. This innovative catalyst design strategy holds great promise achieving highly efficient high-value chemical synthesis under mild conditions.
