Constructing a brand-new advanced oxidation process system composed of MgO₂ nanoparticles and MgNCN/MgO nanocomposites for organic pollutant degradation

Abstract

A brand-new advanced oxidation process (AOP) system consisting of MgO2 nanoparticles and MgNCN/MgO nanocomposites was firstly developed for the degradation of organic pollutants. In the novel AOP system, MgO2 nanoparticles...

Improvement of Carbonyl Groups and Surface Defects in Carbon Nanotubes to Activate Peroxydisulfate for Tetracycline Degradation

“…Recently, advanced oxidation processes (AOPs) [ 9 , 10 , 11 , 12 ], particularly peroxymonosulfate (PMS) and peroxydisulfate (PDS)-based AOPs [ 13 , 14 , 15 ], have become one of the research hotspots in getting rid of refractory antibiotics due to their virtues like fast reaction rate, high degradation efficiency, no secondary contaminant and wide applicable pH range [ 16 , 17 , 18 ]. So far, a great deal of techniques, including heat [ 19 ], ultraviolet light [ 20 ], ultrasound [ 21 ], transition metal [ 22 ] and carbonaceous material [ 23 , 24 ], have been applied to activate PMS/PDS to produce strong oxidizing reactive oxygen species (ROS) for antibiotic degradation.…”

Fabrication of Nano Iron Oxide–Modified Biochar from Co-Hydrothermal Carbonization of Microalgae and Fe(II) Salt for Efficient Removal of Rhodamine B

“…Recently, the content of organic pollutants in the environment has been increasing due to the rapid development of industry, leading to severe environmental issues [1][2][3][4]. Specifically, the disposed water from the textile, printing, cosmetics, medicine and other industries contains a significantly high amount of organic dye molecules which are potentially carcinogenic and teratogenic with high toxicity, posing a serious threat to various organisms and human health [5,6].…”
