Sun, Ping; Liu, Hui; Zhai, Zhicai; Zhang, Xuesheng; Fang, Yingsen; Tan, Jun; Wu, Jiaqiang published an article on January 15 ,2019. The article was titled 《Degradation of UV filter BP-1 with nitrogen-doped industrial graphene as a metal-free catalyst of peroxymonosulfate activation》, and you may find the article in Chemical Engineering Journal (Amsterdam, Netherlands).Application In Synthesis of Triacetonamine The information in the text is summarized as follows:
Instead of previously reported graphene oxide (GO), industrial graphene (reduced graphene oxide (IrGO)) was annealed with a nitrogen precursor. The obtained nitrogen-doped graphene (N-IrGO) was then employed as a novel catalyst for peroxymonosulfate (PMS) activation to degrade benzophenone-1 (BP-1) for the first time. The results show that N-IrGO exhibits excellent catalytic performance over conventional GO and its nitrogen-doped sample and was even better than the metal catalysts Co3O4 and Fe3O4. The enhanced catalytic performance might be attributed to graphitic-like nitrogen. Moreover, the effects of various factors were studied, including catalyst load, PMS concentration and reaction temperature Possible degradation pathways of BP-1 in the N-IrGO/PMS system were proposed based on detected intermediates and the frontier electron d. calculation Radical quenching experiments and ESR (EPR) tests indicated that nonradical oxidation (singlet oxygen (1O2)) plays a dominant role in the BP-1 degradation, in contrast to the previously proposed radical process. Finally, mineralization and stability experiments confirmed that N-IrGO may be an alternative catalyst for environmental remediation. This study contributes to designing novel graphene materials with N doping and gives new insight into nonradical oxidation on benzophenone-type UV filters degradation The results came from multiple reactions, including the reaction of Triacetonamine(cas: 826-36-8Application In Synthesis of 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.Application In Synthesis of Triacetonamine
