We report a facile surface fluorination strategy for restricting Pt nanoparticle sintering through providing anchoring sites on the TiO2 support and enhancing metal-support interaction via improved electronic interaction without sacrificing the active sites. The fluorine-tailored Pt/TiO2 exhibits excellent sintering resistance and significant activity enhancement in the catalytic oxidation of toluene.
我们报道了一种简便的表面氟化策略，该策略通过在TiO₂载体上提供锚固位点，并通过改善电子相互作用增强金属-载体相互作用，同时不牺牲活性位点，从而限制铂纳米颗粒的烧结。经氟修饰的Pt/TiO₂在甲苯催化氧化中表现出优异的抗烧结性能和显著的活性增强。
