The Influence of the Polymeric Matrix on the Development and Ageing of Ni(II)- and Co(II)-Containing Catalysts upon the Liquid-Phase Oxidation of Sulfide-Anion by Oxygen

Abstract

The oxidation of S2--ion by molecular oxygen over Ni(II)- and Co(II)-containing catalysts has been investigated. It was shown that effects of the development and ageing of catalysts during reaction connected with the metal ion nature and with the presence or absence of polyacrylamide hydrogel as support. Duration of the period of the catalyst development depends on conditions of formation of a sulphide phase and doesn’t connect with catalitic properties of nickel and cobalt sulphides. The changing of gel cross-linkage from 1 to 10% doesn’t affect the activity and stability of catalysts.
