Recent Research from Nanjing University of Science and Technology Highlight Findings in Chemicals and Chemistry (Reduced Mgfe Hydrotalcite Efficiently Catalyzes the Aerobic Oxidation of Alkylarenes)

2023 JUL 24 (NewsRx) -- By a News Reporter-Staff News Editor at Chemicals & Chemistry Daily -- Investigators publish new report on Chemicals and Chemistry.

Article Description

A new catalyst containing redox couple Fe 2+ / Fe 3+ and oxygen vacancies has been developed via reduction of MgFe hydrotalcite (MgFe-LDH) by NaBH 4. It has been found that oxygen vacancies positively influence the catalytic property of reductive MgFe-LDH (MgFe-LDH(R)). MgFe-LDH(R) showed excellent catalytic activity in the alkylarenes oxidation with molecular oxygen in the absence of additives. Various alkylarenes were compatible with the MgFe-LDH(R) catalytic system with high conversions and selectivities. The kinetic study, controlled experiments, TPD experiments and DFT study demonstrated that the positive catalytic activity were related to a greater number of oxygen vacancies, the capacity to produce singlet oxygen and superoxide radicals and increased amount of low valent states of iron.
