Mg doped CuO–Fe2O3 composites activated by persulfate as highly active heterogeneous catalysts for the degradation of organic pollutants
TL;DR: In this article, the performance of Mg doping improved the catalytic performance of CuO-Fe2O3 for phenol degradation as the removal efficiency of phenol reached up to 84.36% within 45min using 3.2% Mg doped CuO -Fe 2O3 when coupled with persulfate (PS) system.

TL;DR: 1O2, O2·-, ·OH and SO4•- were identified as the active species in Mg-doped Ni(OH)2/PS system for phenol degradation and a degradation mechanism was proposed for this system.
Degradation of orange II by Fe@Fe2O3 core shell nanomaterials assisted by NaHSO3.
TL;DR: The oxidation efficiency was highly improved due to rapid electron transfer between Fe core and Fe2O3 shell, which promoted the direct recycling of ≡Fe3+ and ≡Fe2+ and thus accelerated the generation of SO4- and OH radicals.
Degradation of dye in wastewater by Homogeneous Fe(VI)/NaHSO3 system.
TL;DR: The high oxidation potential ofFe(VI) and other species such as sulfate and hydroxyl radicals were responsible for the outstanding capabilities of Fe(VI)/NaHSO3 system, which could significantly improve the treatment of organics in wastewater under a very wide range of pH conditions.
