We report the formation of MgCoSiO4 materials by a high-temperature solid-state reaction, a molten salt method and a mixed solvothermal approach. The preparation process had a profound effect on the morphology and particle size of the materials. Mesoporous MgCoSiO4 was obtained for the first time by...
