Comparative study of PMS oxidation with Fenton oxidation as an advanced oxidation process for Co-EDTA decomplexation

Breathable Bactericide Piezocatalyst Integrating Anode–Cathode Heterojunction Capacitance on a Piezoelectric–Conductive Film

“…Figure k shows the H 2 O 2 decomposition rates catalyzed by the rGO-Co­(OH) 2 @PHC composites by adding external H 2 O 2 . The decomposition of H 2 O 2 accelerates with increased duration of the Co­(OH) 2 deposition, indicating that cobalt­(II) effectively catalyzes the decomposition of H 2 O 2 . , …”

Self-propelled Janus magnetic micromotors as peroxidase-like nanozyme for colorimetric detection and removal of hydroquinone

“…where SD is the standard deviation of blank samples tested multiple times and m is the slope of the calibration curve. Thus, LOD was calculated to be 0.0923 μM using eqn (15) according to the noise ratio S/N = 3. In addition, the constructed micromotors for HQ detection experiments were compared with other reported strategies.…”

“…In addition, AOPs such as the Fenton oxidation process have attracted great attention due to their high oxidation capacity, low selectivity, fast reaction speed, high treatment efficiency, effective reduction of trichloromethane production and convenient operation. 14–16…”

“…In addition, AOPs such as the Fenton oxidation process have attracted great attention due to their high oxidation capacity, low selectivity, fast reaction speed, high treatment efficiency, effective reduction of trichloromethane production and convenient operation. [14][15][16] The Fenton reaction/Fenton-like reaction plays an important role in the process of Fenton oxidative degradation, which can degrade a variety of organic pollutants into pollution-free small molecules such as carbon dioxide (CO 2 ) and H 2 O by catalyzing the decomposition of H 2 O 2 to produce a large number of O 2 and hydroxyl radicals (˙OH) and catalyze the conversion of O 2 to superoxide anions (O 2 ˙−). [17][18][19] At present, most scholars believe that the catalytic mechanism of peroxide mimicking nanozymes is based on the Fenton/Fenton-like reaction.…”

Photocatalytic activity study of ZnO modified with nitrogen–sulfur co-doped carbon quantum dots under visible light

“…1 Notably, levels of dissolved organic dye pollutants in the vast majority of water bodies exceed the acceptable standards for human consumption, leading to a lack of clean water in many communities around the world. 2 Recently, advanced oxidation processes (AOPs) (including photochemical oxidation, [3][4][5] catalytic wet oxidation, 6 sonochemical oxidation, 7 electrochemical oxidation, [8][9][10][11] Fenton oxidation, 12 etc.) for wastewater treatment based on reactive oxygen species (ROS) have attracted wide attention from researchers.…”
