Heterogeneous Fenton-like reactions based on nonradical reactive oxygen species (ROS) are desirable for selective water decontamination, and different pollutants coexisting in real scenarios necessitate a rational combination of multiple ROS efficient sustainable decontamination. However, the general one-catalyst-for-one-ROS strategy toward generation inevitably renders combinational process lengthy cost ineffective. Herein, we developed new approach to enable separate but two distinct one catalyst via peroxymonosulfate activation. The unique is comprised graphitic layer bottom-wrapped Fe@Fe3C encapsulated inside nitrogen-doped carbon nanotubes. Fe3C shell facilitates formation surface-bound FeIV═O with up 96.0% selectivity, applied electric field could switch free 1O2 90.5% as enabled by C atoms adjacent graphite N. One dual-site enables both high cumulative concentration 16605 7674 μM at 30 min, respectively. Based such simple electricity on/off mode, tandem operated unit was proposed efficiently degrade mixed adsorption properties. This study presents very effective modulate that simplifies systems
