| 英文摘要 | Inspired by living systems, the construction of smart devices that can self-heal in response to structural damage is a promising technology for maintaining the high activity and stability of catalysts during heterocatalytic reactions. Here this study demonstrates an ingenious platform that enabled efficient persulfate (PS) activation for contaminant degradation via integrating a catalyst with photoactuation regeneration. Under irradiation, it is unambiguously confirmed that the collective properties of a tailored FeOOH@C3N4 catalyst permit interfacial photoexcited electron transport from the photocatalyst substrate to needle-shaped FeOOH. This results in the simultaneous recovery of Fe(III) and optimization of the Fe(II)/Fe(III) ratio on FeOOH surface during PS activation process, so that the healed chemical structure ensures that subsequent PS activation remains unimpaired. Aqueous organic contaminant (bisphenol A) oxidation efficacy in this system is almost 20 times higher than for photo- or Fenton-oxidation alone. This work highlights the concept of catalyst regeneration for stable reactive species generation in solution, which represents alternative application of photocatalysis for practical environmental remediation. Further, the photoactuation healing approach can be expanded into various domains, such as material fabrication or chemical synthesis. |
