“…A plausible mechanism for the oxidation is shown in Scheme 4 based on literature, 25 our observations and obtained results, catalytic activity of KBr (Scheme 5) and in situ generation of HOCl by the use of trichloroisocyanuric acid in the presence of water. 22c, 26,27 The oxidation of bromide ion by HOCl would give hypobromous acid 25 and subsequent oxidation of alcohols affords aldehydes and ketones.…”

“…[3,22] The sole PMS can yield 87% BzH in homogeneous environment, while extra additives are still needed. [23] The selectivity of SACo@NG is also higher than radical based BzOH oxidation by carbon nanotubes activated PMS (80.1%), [20] suggesting the intrinsic oxidation mechanism over SACo@NG may differ from the metal-free activated PMS oxidation. Compared with Co NPs, the Co SACs exposed more active sites for PMS activation thus the BzOH oxidation rate is greatly enhanced.…”

[3] Precious metals such as platinum, ruthenium, gold, and palladium are found to afford excellent catalytic activity for the selective oxidation of alcohols, [2a,4] however, their scarcity and high cost hinder the real applications for chemical industry. As an alternative, the catalysts based on earth-abundant transition metals are investigated to activate different oxidants including molecular oxygen, ozone, and liquid peroxides (i.e., hydrogen peroxide and tert-butylhydroperoxide) for oxidative applications. [5] The particle size and dispersion of the metal/ metal oxides play a pivotal role in affecting the catalytic performance. Therefore, much attention has been focused on reducing the particle size and optimizing the coordination between the metals and supports. Graphene based materials are extensively studied as substrate to support highly dispersed metal particles owing to the high surface area and excellent chemical/electrochemical properties. [6] Single-atom catalysts (SACs) consist of individual atoms dispersed on and/or bonded with the surface atoms of an appropriate support with high selectivity, catalytic activity and excellent atomic efficiency.

The electrochemical oxidation of benzyl and substituted benzyl alcohols including primary and secondary alcohols and piperonyl alcohol was carried out in an undivided cell using platinum electrodes in a biphasic medium using Cl À /OCl À as the redox mediator. In most cases, selective oxidation of alcohols to the corresponding aldehydes or ketones was achieved with high yields of products by the in situ generated chloronium ion. This method is simple and gives better yields of products compared with chemical methods of oxidation.
