The article was 《Promoted peroxymonosulfate activation into singlet oxygen over perovskite for ofloxacin degradation by controlling the oxygen defect concentration》. The article mentions the following:
Recently, perovskite is becoming a promising alternative as peroxymonosulfate (PMS) activator for the remediation of organic pollutants in water. But the factor determining PMS activation efficiency of perovskite and the evolution of reactive oxygen species (ROS) remain equivocal and elusive. In this study, we proposed an oxygen defect dependent PMS activation mechanism over perovskite with the singlet oxygen (1O2) as the dominant ROS. Among the tested four perovskites, ofloxacin (OFX) degradation efficiency increased with the following order: LaFeO3 < LaZnO3 < LaMnO3 < LaNiO3, which agreed well with their oxygen defect amounts based on XPS and ESR (EPR) anal. The results clearly demonstrated a good relationship among oxygen defects in LaBO3, OFX degradation efficiency and 1O2 concentration Moreover, 1O2 evolution mechanism over perovskite by decreasing the activation energy of PMS self-decomposition was proposed. The 1O2 mediated OFX degradation pathway was further studied by HPLC-MS technique and three-dimensional excitation-emission matrix fluorescence spectroscopy (3D EEMs). This work provides a new insight into PMS activation by perovskites and favors its application in actual water treatment. In the experiment, the researchers used many compounds, for example, Triacetonamine(cas: 826-36-8Recommanded Product: Triacetonamine)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine-containing compounds are also frequently employed in synthesis as ligands or auxiliaries. Accordingly, many efforts have been devoted to the development of novel methods for the synthesis of these compounds over the years.Recommanded Product: Triacetonamine
