英文摘要	Catalytic membranes as heterogeneous advanced oxidation microreactors are appealing for persistent organic pollutants (Pops) treatment. Constructing a robust catalytic membrane with highly active sites for instantaneous and standing mineralization of flowing Pops are challenging in its practical application. Herein, we enable in-situ growth and firm enchasing of Prussian blue (PB) micro-crystals in the micro-clusters of Polyvinylidene fluoride (PVDF) membrane, where active sites are fully exposed for oxidant reagent and target contaminants. The designed PB@PVDF catalytic membrane demonstrates exceptional efficiency for instantaneous degradation of recalcitrant organic molecules e.g. bisphenol A, methylene blue, rhodamine B as well as humic acid. The membrane maintains high removal efficiency above 99% for MB with a constant flux of 300 Lm(-2) h(-1) during a long-term (24 h) cross-flow test. Both the enrichment of radials and pollutants in confined tortuous micro-pores and prompt flowing away of degraded products lead to the superior catalytic activity of heterogeneous Fenton reactors.
