Abstract

Functional materials based on highly dispersed amorphous silica and cobalt compounds have been obtained by solvothermal and mechanochemical methods. The formation of silicate Co3(Si2O5)2(OH)2 under hydrothermal conditions has been established. This composition, in comparison with mechano-mixes, provides better photoactivity in the hydroquinone decomposition reaction under ultraviolet irradiation, herewith maintaining the surface characteristics of amorphous SiO2.
