Gao, Yaowen;Zhu, Yue;Chen, Zhenhuan;Hu, Chun research published 《 Nitrogen-Coordinated Cobalt Embedded in a Hollow Carbon Polyhedron for Superior Catalytic Oxidation of Organic Contaminants with Peroxymonosulfate》, the research content is summarized as follows. The search for high-active and long-lasting materials is of paramount significance for elimination of aqueous organic contaminants. Herein, a nitrogen-coordinated cobalt embedded in hollow carbon polyhedron (marked as NCoHCP) has been synthesized by thermal transformation of core-shell-architectured ZIF-8@ZIF-67. XPS, X-ray absorption spectroscopy (XAS), and theor. calculations confirmed the coordination of a Co atom with one N atom in NCoHCP. The resultant NCoHCP catalyst delivers extremely superior catalytic performance in peroxymonosulfate (PMS) decomposition into active species toward complete oxidation of organic pollutants in less than 45 s. Exptl. data and theor. computations disclosed the formation of Co-pyridinic N moiety not only creates the Co species with higher electron d. as active sites but also increases the C atom neighboring pyridinic N with lower electron d. as binding sites for PMS conversion toward reactive oxygen species generation to oxidize organic pollutant. On the other hand, the donation of electron from organic contaminant toward the C atom adjacent to pyridinic N also induces organic contaminant oxidation The dual-pathway degradation contributes to superior catalytic oxidation of organics over NCoHCP. This study furnishes an effective strategy for developing high-performance and robust metal/carbon hybrid materials toward wide environmental applications.

TEMPO is an intermediate used in the preparation of Piperidinyloxy free radical derivatives.
TEMPO is an organic compound that acts as a radical scavenger. It is stable in the presence of water and air and can be used for the inhibition of bacterial growth. TEMPO reacts with reactive intermediates to form non-reactive substances and terminate chain reactions. This process is optimal at temperatures between 0°C and 40°C and pH values between 3.5 and 7.5. TEMPO has been shown to inhibit the growth of bacteria by reacting with reactive molecules such as amines, chlorides, or low energy radicals in aqueous solution. TEMPO also has genotoxic activity that inhibits DNA synthesis in bacterial cells through oxidation of guanine residues on DNA molecules., Recommanded Product: 2,2,6,6-Tetramethyl-4-piperidinol
