To understand the different surface oxygen species on CNTs for the activation of PMS, density functional theory (DFT) calculations were performed to investigate the adsorption behavior of PMS on various CNTs. The electrophilic oxygen was identified as the electron captor to activate PMS by O–O bond cleavage to form SO5•– and SO4•– radicals. The insight achieved from this fundamental study may be further applied to other organic syntheses via selective oxidation. Peroxymonosulfate (PMS) is a cheap, stable, and soluble solid oxidant, holding promise for organic oxidation reactions. Learn more. The rate-of-production analysis indicates that the consumption of A1CH2OH is dominated by H-abstraction reactions giving rise to A1CHOH, followed by the reaction sequence of A1CHOH→ A1CHO→ A1CO→ A1-→ A1OO→ A1O→ A1OH.

Importantly, it is found that the electrocatalytic oxidation of benzyl alcohol to benzoic acid on Co 0.83 Ni 0.17 /AC is more favourable than the OER process, with almost 224 mV less overpotential at 10 mA cm −2 and 96% faradaic efficiency at 1.425 V vs. RHE (passing charge amount of ∼40C). Herein, we report the catalytic PMS activation via carbon nanotubes (CNTs) for the selective oxidation of BzOH under mild conditions without other additives. Benzyl Alcohol Oxidation on Carbon‐Supported Pd Nanoparticles: Elucidating the Reaction Mechanism. The following experimental parameters were varied: the initial benzyl alcohol concentration, the oxygen partial pressure in the headspace, and the reactor temperature.

Reaction of A1OH and O2 producing A1O and HO2 presents a strong inhibiting effect at both conditions. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.)

The atmospheric oxidation of benzyl alcohol (A1CH2OH) has been investigated in a jet-stirred reactor (JSR) at equivalence ratios of 0.4 and 2.0 within 700–1100 K. Mole fraction profiles of 19 species were analyzed by online GC and GC/MS techniques. The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online.
