Formation of Copper-Containing Particles on the Quartz Surface as a Result of the Photolysis of Copper(II) Complexes with Amino Acids

Abstract

Island copper-containing films consisting mainly of copper(I) oxide particles were obtained on a quartz surface by photochemical decomposition of copper(II) complex compounds with amino acids. The size and morphology of Cu₂O particles and their dependence on the photolysis duration and the amino acid nature contained in the complex were established. The films obtained by the complex [Cu(β-Ala)₂] photolysis have the highest photocatalytic activity in reactions of methyl orange photodecomposition.
