Lattice B-doping evolved ferromagnetic perovskite-like catalyst for enhancing persulfate-based degradation of norfloxacin

Synthesis and characterization of LaCoxNi1‐xO3 perovskites as heterogeneous catalysts for phenolics degradation by persulfate activation

“…Specifically, 1 O 2 was reported as the dominant ROS for PMS activation by La x NiO 3 , 58 in addition to • OH and SO 4 •‐ . Additionally, as reported elsewhere, 61 concentrations of • OH and SO 4 •‐ produced after activation of PMS by CeCu 0.5 Co 0.5 O 3 perovskite at 180 min were found to be 0.52 and 10.91 μmol L −1 , respectively. Many studies reported that 1 O 2 can be formed in a LaBO 3 /PMS system after the oxidation of the B metals during the activation of PMS 26,28 …”

Construction of macroporous MOF-derived single leaf-like cellular skeleton for boosting advanced oxidation processes

“…The SM-NiCoO v -S firstly expressed a larger adsorption capacity towards NOR than other catalysts involving metallic oxides, MOF-derived cases and single-atom catalysts (SACs), etc. 4,5,13–26 Additionally, the active sites from Co, Ni and oxygen vacancies synergistically assisted our sample with faster reaction dynamics. Along with the promising degradation rate, reliable cyclability and strong pH tolerance, the SM-NiCoO v -S was distinguished among those state-of-the-art catalysts.…”

“…The current abuse of NOR has caused serious environmental problems, since it is difficult to remove by conventional wastewater purication techniques because of NOR's antimicrobial characteristics, which is chemically stable and resistant to biodegradation; thus, it has been found in sediments, groundwater and rivers. [5][6][7][8] To deal with the evergrowing pollution, advanced oxidation processes (AOPs), which generate highly reactive oxygen species (ROS) using catalysts, have recently attracted great attention, since the as-generated ROS can fully decompose the refractory organic molecules. [9][10][11][12][13] As one of the most efficient AOPs, peroxymonosulfate (PMS)-AOPs not only can produce ROS such as cOH, SO 4 c − and cO 2 − , [14][15][16][17][18][19][20][21][22][23][24][25][26] but also afford nonradical species such as singlet oxygen ( 1 O 2 ) for organics degradation in various working environments, hence satisfying the process diversity.…”

In situ growth of an ultrathin Cu/g-C3N4 coating over SBA-15 for catalytic wet air oxidation of pollutants under extremely mild conditions

“…As compared with Cu 1 @SBA-N, the Cu 2p peaks of Cu 1 /CN 3.3 @SBA-N also shifted to the high-energy region, indicating the existence of the C 3 N 4 thin layer on the surface of SBA-15. The higher Cu + content in Cu 1 /CN 3.3 @SBA-N was caused by the strong interaction between Cu and g-C 3 N 4 , 57 which explains why Cu 2 O was detected in the XRD pattern in Fig. 7.…”
