Organic contaminants degradation from the S(IV) autoxidation process catalyzed by ferrous-manganous ions: A noticeable Mn(III) oxidation process.
TL;DR: This work investigated the characteristics of the Fe2-Mn2+/sulfite process in the presence of organic contaminants, which might promote the development of Mn(III) oxidation technology.
Journal ArticleDOI

Congwei Luo,Daoji Wu,Lu Gan,Xiaoxiang Cheng,Qiao Ma,Tan Fengxun,Jing Gao,Weiwei Zhou,Shishun Wang,Fumiao Zhang,Jun Ma +10 more
TL;DR: In this paper, the degradation of Congo Red (CR) in thermally activated persulfate (PDS) oxidation (TAP) system was investigated, and the calculated activation energy of CR in TAP system was approximately 76(± 0.8) KJ mol−1 within the range of 313-353 K, and CR could be degraded effectively.
Journal ArticleDOI
Dechlorination of chloroacetic acids by Pd/Fe nanoparticles: Effect of drying method on metallic activity and the parameter optimization
TL;DR: In this article, two kinds of dry Pd/Fe nanoparticles were obtained by drying the laboratory synthesized wet Pd and Fe nanoparticles with direct oven drying method and solvent replacement ozone drying method, respectively.
Journal ArticleDOI
Highly efficient simultaneous catalytic degradation and defluorination of perfluorooctanoic acid by the H2O2-carbon/MnO2 system generating O2- and OH synchronously
TL;DR: In this paper, carbon/MnO2 composites were synthesized to treat perfluorooctanoic acid (PFOA) for the first time and achieved high degradation and defluorination efficiencies within 15 minutes.
Journal ArticleDOI
A Polymer-Reinforced SEI Layer Induced by a Cyclic Carbonate-Based Polymer Electrolyte Boosting 4.45 V LiCoO2/Li Metal Batteries
Rongxiang Hu,Huayu Qiu,Huanrui Zhang,Peng Wang,Xiaofan Du,Jun Ma,Tianyuan Wu,Chenglong Lu,Xinhong Zhou,Guanglei Cui +9 more
TL;DR: The as-investigated gel polymer electrolyte (GPE) assembled LiCoO2 /Li metal batteries exhibit a fantastic cyclability with a capacity retention of 92% after 200 cycles at 0.5 C, evidently exceeding that of the counterpart using liquid electrolytes.
