The article was titled 《Activation of peroxymonosulfate by iron-biochar composites: Comparison of nanoscale Fe with single-atom Fe》, and you may find the article in Journal of Colloid and Interface Science.Recommanded Product: 826-36-8 The information in the text is summarized as follows:
A convenient and efficient method to fabricate isolated Fe single-atom catalysts deposited on Myriophyllum aquaticum-based biochar (ISA-Fe/MC) is reported for peroxymonosulfate-based organics degradation Firstly, the Fe nanoparticles anchored on the hierarchical porous biochar (nano-Fe/MC) can be obtained by utilizing K2FeO4 as a synchronous activation and graphitization agent. Subsequently, ISA-Fe/MC was achieved by HCl etching of nano-Fe/MC to remove the excess Fe nanoparticles. Compared with nano-Fe/MC, ISA-Fe/MC demonstrated outperformed catalytic capacity towards PMS activation for phenol degradation The combination of super high surface area, hierarchical porous structure, graphitization structure and atomically dispersed Fe species should be responsible for prominent catalytic oxidation ability and outstanding resistance to common anions and humic acid. Based on the chem. scavengers, EPR experiments and electrochem. tests, the SO•-4 dominated radical degradation pathway for nano-Fe/MC and electron transfer reigned non-radical degradation pathway for ISA-Fe/MC was revealed. In contrast to nano-Fe/MC, d. functional theory calculations demonstrated the enhanced d. of states around Fermi level in ISA-Fe/MC meaning the increased catalytic performance and more electron transfer between single-atom Fe to adjacent graphitic C and N which could serve as electron transfer channel for PMS activation. In the experimental materials used by the author, we found Triacetonamine(cas: 826-36-8Recommanded Product: 826-36-8)
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: 826-36-8
