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.

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.

Cation Effect

Abstract The energy efficiency of the microwave-assisted synthesis of pyrrolidinones was demonstrated using catalytic loading of 1,1’-butylene-bis(3-sulfo-3H-imidazol-1-ium) chloride as a sulfonic acid functionalized ionic liquid in ethylene glycol as green solvent. The effect of electron donating and electron withdrawing groups on aniline derivatives was studied under conventional heating and microwave irradiation. Furthermore, the cation effect of ionic liquids containing sulfonic groups on the catalytic efficiency for the synthesis of ethyl-1-phenyl-2-(4-chlorophenyl)-4-hydroxy-5-oxo-2,5-dihydro-1H-pyr-role-3-carboxylate was investigated under conventional heat. The experimental results exhibited that there is a relationship between catalytic efficiency and the number of sulfonic groups and imidazolium moieties linked by carbon spacer.
