Accelerated charge transfer in well-designed S-scheme Fe@TiO/Boron carbon nitride heterostructures for high performance tetracycline removal and selective photo-reduction of CO greenhouse gas into CH fuel.

Abstract in brief

• The study reports the synthesis of a new FeTiOBoron Carbon Nitride (FTBCN) heterostructure that effectively degrades tetracycline antibiotic and selectively converts CO into CH fuel under visible light, with the FT30BCN sample achieving 96.3% tetracycline degradation in 60 minutes and significantly higher efficiency compared to bare boron carbon nitride.
• The FTBCN photocatalyst demonstrates remarkable improvement in CO photoreduction, showing high hydrogen (CH) and carbon monoxide (CO) evolution rates, thanks to enhanced light absorption, charge separation, and the heterojunction between FeTiO and boron carbon nitride that facilitates efficient charge transfer through an S-scheme mechanism.
• The research also investigates various reaction conditions, such as pH, electrolytes, and water matrices, as well as modifications like alkali activation and varying feed ratios, all of which optimize the photocatalytic performance and selectivity for both tetracycline removal and CO-to-CH conversion.]
