Outline
This study addresses challenges in conventional advanced oxidation processes (AOPs), including mass transfer limitations of endogenous mediators, and reliance on energy-intensive/sacrificial agents' consumption to maintain the catalytic activity, by proposing an innovative strategy that employs trace H2O2 to micro-regulate dual-reaction center (DRC) catalysts for enhanced water self-purification. DRC catalyst (FZSO) with surface electron-polarized distribution can effectively enhance interactions between naturally dissolved oxygen and pollutants, thereby overcomes mass transfer limitations and obviously enhances water self-purification. This process radically changes the role of H2O2—innovatively repurposed from the sacrificial agent in AOPs to the precision micro-regulator in DRC system, largely reducing consumption in water treatment. Experimental results demonstrate that under micro-regulation with only 1mmol/L H2O2, the FZSO-DRC system achieved complete ciprofloxacin removal within 15min, with less than 10% H2O2 consumption. FZSO system also exhibits strong adaptability and stability for complex water matrices (pH or salinity ions). This study proposes a breakthrough in energy-efficient water purification by amplifying natural water self-purification capacity through the FZSO-DRC system, providing new technical perspective for developing high-efficiency, low-consumption water treatment processes.
