Enhanced mechanism of copper doping in magnetic biochar for peroxymonosulfate activation and sulfamethoxazole degradation

Peroxymonosulfate activation by Fe–Mn Co-doped biochar for carbamazepine degradation

“… 25 Meanwhile, bimetallic doping decreases the infusion of metal ions, which also reduces the toxicity of the catalyst and makes the process more environmentally friendly. 26 In particular, Fe and Mn are inexpensive and environmentally friendly. 27 The generation of magnetic Fe oxides enhances the separability of catalysts.…”
