    Article Snippet: A pure non-metallic catalyst, the nitrogen doped hydrothermal carbon (NHCs) which can be comparable to zerovalence-iron, was designed for activation of peroxymonosulfate (PMS) and peroxydisulfate (PDS) assisted by ultrasonic-mechanochemical action.. NHCs were prepared via hydrothermal and heat treatments with N sources (melamine derived carbon nitride) and C sources (glucose derived hydrothermal carbon), and the range of preparation temperature of efficacious NHCs was around 400–800 C. The excess N source (carbon nitride/ glucose at 2.00 g/0.50 g) can observably improve the activation ability of NHCs.. Especially, the optimal NHCs under ultrasonic driving showed efficient catalytic capability for PMS, 10 mg NHCs could effectively activate 0.75 mmol PMS (the mass ratio at 1:25) for > 90 % removal of contaminant within 10 min (kapp = 0.3653 min 1).
