摘要
Sulfite (S(IV))-based advanced oxidation methods are a promising new approach to dealing with organic pollutants. In this study, the catalyst P-ZIF67@BC500, which exhibits superior physicochemical properties, was employed to activate S(IV) for bisphenol S (BPS) degradation. The findings indicate that pyrolysis temperature plays a critical role in modulating the physicochemical characteristics, activation mechanisms, and degradation capacity of the catalysts. Notably, the P-ZIF67@BC500/S(IV) system demonstrated optimal performance, achieving a 95 % degradation of BPS within 15 min of reaction. Furthermore, this catalyst exhibited exceptional stability, maintaining its activity over seven consecutive cycles. Its broad applicability in water treatment is further demonstrated by its capacity to eliminate over 90 % of different organic contaminants. Six BPS intermediates were found via a thorough mechanistic investigation, which shed light on the catalytic mechanism. The study's overall findings demonstrate P-ZIF67@BC500's potential as a highly efficient catalyst for sophisticated water treatment applications by activating S(IV). The effective elimination of organic compounds indicates its suitability for advancing environmentally friendly and high-performing water treatment systems.
