Ren, Wei;Xiong, Liangliang;Yuan, Xuehong;Yu, Ziwei;Zhang, Hui;Duan, Xiaoguang;Wang, Shaobin research published 《 Activation of Peroxydisulfate on Carbon Nanotubes: Electron-Transfer Mechanism》, the research content is summarized as follows. This study proposed an electrochem. technique for studying the nonradical oxidation pathway of organics in C nanotubes (CNTs)-catalyzed peroxydisulfate (PDS) activation. The half-wave potentials of twelve phenolic compounds (PCs) were evaluated and correlated to their kinetic rate constants in the PDS/CNTs system. Integrated with quant. structure-activity relations (QSARs), EPR and radical scavenging tests, the nature of nonradical pathway was unveiled to be an electron-transfer regime without singlet oxygenation process. The QSARs accurately predicted the oxidation process of PCs according to their standard electrode potentials, reactive pH and temperature A novel electrochem. anal. method (transient open circuit potential combined with chronoamperometry) was employed to probe the mechanism, suggesting that PDS was firstly catalyzed by CNTs to form a surface-confined CNTs-PDS* complex with a high redox potential. Then, the CNTs-PDS* selectively abstracted electrons from the co-adsorbed PCs to initiate the oxidation Finally, a comparison of PDS/CNTs and graphite anodic oxidation under constant potentials was comprehensively analyzed to unveil the relative activity of the nonradical CNTs-PDS complexes toward different PCs, which was determined by the oxidative potentials of the CNTs-PDS* complex and the adsorbed organics
2403-88-5, 2,2,6,6-Tetramethyl-4-piperidinol(TEMPO) is a useful research compound. Its molecular formula is C9H19NO and its molecular weight is 157.25 g/mol. The purity is usually 95%.
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
