Regulating the distribution of reactive oxygen species generated from H2 O2 activation is prerequisite to ensuring efficient and safe use in chemistry life science fields. Herein, we demonstrate that constructing a dual Cu-Fe site through self-assembly single-atomic-layered Cu5 nanoclusters onto FeS2 surface achieves selective with high efficiency. Unlike its unitary Cu or Fe counterpart, sites residing at perimeter zone /FeS2 interface facilitate adsorption barrierless decomposition into ⋅OH via forming bridging Cu-O-O-Fe complex. The robust situ formation governed by this atomic-layered catalyst enables effective oxidation several refractory toxic pollutants across broad pH range, including alachlor, sulfadimidine, p-nitrobenzoic acid, p-chlorophenol, p-chloronitrobenzene. This work highlights concept building catalytic manipulating on molecular level towards environmental control beyond.
