Hydroxylamine-Enhanced NiFe2O4/H2O2 Fenton-like System for Phenol Degradation at an Initial pH of 7: Performance and Mechanistic Insights

A major limitation hindering the practical application of heterogeneous Fenton-like systems is their inherently slow reaction kinetics, particularly near neutral pH. To address this issue, a hydroxylamine (HA)-enhanced NiFe2O4/H2O2 system was developed for phenol degradation. At...

Preparation of Oil Sludge-Based Activated Carbon Loaded with CuO/Fe2O3 and Its Mechanism in Activating Peroxymonosulfate for p-Nitrophenol Degradation

In this study, oil sludge was utilized as a carbon source to prepare a carbon-based catalyst. By leveraging the oil sludge’s inherent iron content and subsequently introducing exogenous copper, a CuO/Fe2O3/carbon composite material (OSC-0.75Cu) was synthesized for the activation...
