Preparation of catalytically active membranes based on copper oxide (II) sol-gel method
Aggregate stabile composition based on hydrosol CuO has been synthesized, it is suitable for the formation of CuO layers deposited on the surface of various media. The conditions of the main stages of the sol-gel process, which allows to obtain layers of CuO on the surface of ceramic microfiltration membranes are determined. The membranes are shown to exhibit catalytic activity in liquid-phase reaction of phenol oxidation, which is carried out under mild conditions.
