Zhao, Zhendong; Zhou, Wenjun; Lin, Daohui; Zhu, Lizhong; Xing, Baoshan; Liu, Zhiqi published an article in Applied Catalysis, B: Environmental. The title of the article was 《Construction of dual active sites on diatomic metal (FeCo-N/C-x) catalysts for enhanced Fenton-like catalysis》.Name: Triacetonamine The author mentioned the following in the article:
High metal loading of single-atom catalysts enables excellent catalytic activity, but possibly causes serious aggregation problem. Herein, a series of diat. FeCo-N/C-x (x represents metal content) were skillfully designed and applied to improve the catalytic activity for peroxymonosulfate (PMS) activation toward degrading organic micropollutants. The unprecedented dual active sites, referring to Fe(N3)-Co(N3) moiety and FeCo alloy, are constructed on the obtained FeCo-N/C-x, thereby exhibiting significantly greater performance toward degrading aqueous phenol (e.g., 0.316 min-1 for FeCo-N/C-3) via PMS activation, compared with those of traditional single-atom Co-N/C (0.011 min-1) and Fe-N/C (0.018 min-1). Combined exptl. and theor. calculations demonstrate the independent functions of dual active sites, in which Fe(N3)-Co(N3) and FeCo alloy can decrease the energy barrier of O-O bond cleaving resulting in the formation of high-valent FeCo=O reactive species and singlet oxygen, resp. This study opens up a new platform toward constructing dual active sites for enhanced Fenton-like catalytic activity. In the experiment, the researchers used Triacetonamine(cas: 826-36-8Name: Triacetonamine)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine is ubiquitous structural motif widely occurred in diverse synthetically and naturally occurring bioactive molecules. Piperidines are an immensely important class of compounds medicinally: the piperidine ring is the most common heterocyclic subunit among FDA approved drugs.Name: Triacetonamine
