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.

Keywords: amorphous silica, cobalt silicate, hydrothermal synthesis, highly dispersed material, photocatalyst.
