a Schematic illustration of catalysts with the strain effect. b Time profile of the free chlorine concentration activated by our catalysts. Reaction conditions: 0.1 g L−1 catalyst, 4.5 mg L−1 free chlorine. c EPR technique using DMPO as a spin–trapping agent for the detection of the reactive species shown in (b). d Reactive species analysis during the chlorination process induced by our catalysts. e Spin density of •OH, Cl• and ClO• from our DFT calculations.
