Abstract Selective activation of peroxymonosulfate (PMS) represents an efficient route to generate the reactive oxygen species (ROS) for degradation and deep mineralization organic pollutants, but its activity selectivity are remarkably lower than what is needed. Herein, S‐scheme heterojunction developed effectively modify surface electronic properties introduce abundant vacancies, thereby enabling photo‐enhanced PMS selective removal gaseous toluene. fabricated by in situ growth ultrathin Co 3 O 4 nanoparticles on g‐C N nanosheets through a rapid plasma treatment. The field at heterostructure interface /g‐C (COCN) facilitates charge transfer, selectively removing low‐redox electrons holes while separating high‐redox ones. Photo‐excited promote 3+ /Co 2+ redox cycle, enhancing ROS generation creating continuous sites. COCN catalyst demonstrates high efficiency (90.2%) rate (68.5%) flowing toluene aqueous solution. This study thus provides feasible strategy plasma‐induced modulation offers new insights future design aimed activation.
