The reliance on acidic working environments presents a significant bottleneck in the development and widespread application of peroxymonosulfate (PMS)-activated high-valent iron-oxo systems iron-based catalysts. In this study, we present system non-homogeneous activation that is capable overcoming environment heterogeneous to generate continuous non-radicals for selective degradation organic pollutants such as sulfamethoxazole. takes advantage amphiprotic hydroxides create homogeneous neutral pH microenvironment at interface catalyst. generation inducing formation species more stable cycling iron ions material., promoting sustained catalytic activity A series design quenching experiments, electron paramagnetic resonance (EPR) three-dimensional excitation-emission matrix fluorescence spectroscopy (3D-EEM) which were conducted assess selectivity FeCo-LDH/PMS under high salt or natural conditions, well its effectiveness treating real wastewater. These findings offer novel approach limitations enhancing target advanced oxidation processes (AOPs).
