Oxidation Of Alcohols

Deposition of AuNPs onto a CeO2/C substrate results in the enhanced electrocatalytic activity of the formed AuCeO2/C catalyst for the oxidation reaction of methanol, ethanol, ethylene glycol, and glycerol compared with the prepared Au/C catalyst.

Single crystalline β-Co(OH)2 nanosheets have been synthesized from a layered precursor cobalt(II) acetate hydroxide by microwave heating. The average thickness of β-Co(OH)2 nanosheets is ~10 nm, with particle sizes up to 360 nm. The layered precursor was prepared using Co(CH3COO)2·4H2O, ethylene glycol, and H2O in some cases by microwave heating. Co3O4 nanosheets have been synthesized by hydrothermal oxidation of the layered precursor cobalt(II) acetate hydroxide using H2O2.Key words: nanosheets, microwave, cobalt hydroxide, cobalt oxide.

Glucose Electrooxidation

In this study, the gold nanoparticles (AuNPs) without carbon support were prepared using the well-known citrate reduction method. The carbon supported AuNPs nanocomposites were fabricated by two different approaches: chemical adsorption of AuNPs from the prepared citrate stabilized AuNP colloidal solution on the carbon powder surface and one-pot microwave-assisted synthesis. The nanocomposites were characterized using scanning electron microscopy (SEM) and inductively coupled plasma optical emission spectroscopy (ICP-OES). The electrocatalytic activity of the prepared catalysts was evaluated for the electrooxidation of glucose in an alkaline media using cyclic voltammetry. The highest electrocatalytic activity was observed for the catalyst of carbon supported Au nanoparticles prepared by microwave-assisted synthesis, followed by the catalyst of carbon supported Au nanoparticles prepared by means of the adsorption method, whereas the pure Au nanoparticles without carbon support exhibited the lowest electrocatalytic properties for glucose electrooxidation.
