Strong metal-support interaction between carbon nanotubes and Mn-Fe spinel oxide in boosting peroxymonosulfate activation: Underneath mechanisms and application

Mingjie Huang et al.

Summary: The study reveals how the strong metal-support interaction between carbon nanotubes and Mn0.65Fe2.35O4 boosts peroxymonosulfate activation for rapid degradation of sulfamethoxazole. The synergy induced surface hydroxyl groups and highly hydrophobic CNTs facilitate rapid in situ interfacial degradation of SMX. Furthermore, the SMSI enables accelerated redox cycle rate of Mn species by electron-rich CNTs, resulting in efficient PMS activation.

Ferric ion promoted degradation of acetaminophen with zero - valent copper activated peroxymonosulfate process

Xin Liu et al.

Summary: The Fe(III)/Cu(0)/PMS system significantly enhances the degradation of acetaminophen and removal of total organic carbon by generating multiple reactive oxidants such as Fe(IV), Cu(III), and hydroxyl radical (center dot OH). Fe(IV) and center dot OH play a major role in the degradation of acetaminophen, while Fe(IV), Cu(III), and center dot OH are responsible for the degradation of orange II. Adjusting the final reaction solution to pH 8.0 and subsiding can ensure compliance with environmental standards for total copper discharge.
