Surface-loaded metal nanoparticles for peroxymonosulfate activation: Efficiency and mechanism reconnaissance
Applied Catalysis B: Environmental(2019)
摘要
•Twenty nanoscale metals are comprehensively evaluated as persulfate activators.•Persulfate activation capacity of transition metals sensitively depends on metal type.•Most noble metals outperform Co in terms of persulfate activation efficiency.•Metals are categorized into two groups depending on degradative reaction pathway.•Noble and selected transition metals activate persulfate without radical formation.
