负载型催化剂中的强金属-载体相互作用(SMSI)在催化降解中起主导作用,升级,和环境污染物的再制造。先前的研究表明,SMSI对负载型催化剂的活性和稳定性至关重要。然而,对于在环境催化中催化的氧化还原反应,SMSI诱导的氧空位和电子转移的增强机制有待阐明。此外,SMSI接口站点的精确控制仍有待充分理解。在这里,我们提供了SMSI的催化机制和控制策略在净化气态污染物的系统综述,处理有机废水,以及生物质固体废物的增值。我们通过检查界面电子转移来探索SMSI在氧化还原反应中的吸附和活化机理,界面氧空位,和界面酸性位点。此外,我们从界面效应的系统角度出发,制定了SMSI的精确调控策略,晶面效应,尺寸效应,客体离子掺杂,和改性效果。重要的是,指出了环境催化中SMSI调控的不足和突破方向,包括部分封装策略,规模优化策略,界面氧空位策略,和多成分战略。本文提供了SMSI的潜在应用,并为其在环境催化中的受控调控提供了指导。
The strong metal-support interaction (SMSI) in supported catalysts plays a dominant role in catalytic degradation, upgrading, and remanufacturing of environmental pollutants. Previous studies have shown that SMSI is crucial in supported catalysts\' activity and stability. However, for redox reactions catalyzed in environmental catalysis, the enhancement mechanism of SMSI-induced oxygen vacancy and electron transfer needs to be clarified. Additionally, the precise control of SMSI interface sites remains to be fully understood. Here we provide a systematic review of SMSI\'s catalytic mechanisms and control strategies in purifying gaseous pollutants, treating organic wastewater, and valorizing biomass solid waste. We explore the adsorption and activation mechanisms of SMSI in redox reactions by examining interfacial electron transfer, interfacial oxygen vacancy, and interfacial acidic sites. Furthermore, we develop a precise regulation strategy of SMSI from systematical perspectives of interface effect, crystal facet effect, size effect, guest ion doping, and modification effect. Importantly, we point out the drawbacks and breakthrough directions for SMSI regulation in environmental catalysis, including partial encapsulation strategy, size optimization strategy, interface oxygen vacancy strategy, and multi-component strategy. This review article provides the potential applications of SMSI and offers guidance for its controlled regulation in environmental catalysis.
