摘要:
Radical- and nonradical-based advanced oxidation processes (AOPs) have been widely used as water cleaning technologies. It is a great challenge to achieve a synergy between these two methodologies for enhancing the performance of water purification. Here we report a novel strategy of permanganate (PM)-promoted photocatalytic oxidation by using TiO 2 with different ratios of (101) and (001) facets as model photocatalysts to achieve a synergy of nonradical-radical relay oxidation process. This approach can simultaneously trigger PM activation by photogenerated electrons and result in the selecti...
