Abstract:
This study introduces a sulfur-doped bimetallic active site, demonstrating enhanced mineralization capabilities for pollutant molecules. Specifically, a sulfur-doped iron and molybdenum bimetallic catalyst (F1M1SN) was synthesized and evaluated. In comparison to FN and FMN catalysts, the F1M1SN/H2O2 system exhibited superior catalytic performance, stability, and mineralization efficiency in the degradation of organic pollutants. Notably, the F1M1SN/H2O2 system achieved a 95.9% degradation rate and 73.0% mineralization of tetracycline hydrochloride (TCH). The incorporation of molybdenum facilitates the formation of low-valent iron species, accelerating the Fe2+/Fe3+ redox cycle. Furthermore, sulfur doping, acting as an electron donor, promotes the generation of Mo4+ and Fe2+ species, concurrently broadening the effective pH range to 2-8. Critically, fixed-bed column degradation experiments, designed to simulate realistic operating conditions, confirmed that the F1M1SN/H2O2 system maintained high mineralization levels over a 600-min period. This research establishes a viable catalytic/co-catalytic strategy for the rational design of high-performance iron-based catalysts for H2O2 activation, providing crucial theoretical insights that can advance their practical implementation in water treatment applications.
