Co-aluminosilicate based electrodes

The influence of aluminosilicate support on the catalyst efficiency was investigated. Three different aluminosilicate materials containing cobalt (II) ion as active specie for phenol or nitrite oxidation were obtained. The first sample was zeolite 13X impregnated with Co by impregnation/thermal degradation procedure using Co-acetylacetonate. Bentonite was pillared with Al3+/Co2+ mixture to obtain the second sample. For the third one Co was introduced into Al-pillared bentonite by ion-exchange using Co(NO3)2*6H2O. Reactions of either phenol or nitrite oxidation were used as test reactions for the investigation of the influence of the type of aluminosilicate support on the catalytic activity of Co.
