A novel synthesis strategy leading to the formation of stable transition-metal-oxide mesostructures

摘要

This paper describes a new synthesis strategy of preparing thermally stablemesostructured transition metal oxides, namely, two-step synthesis (TSS).Basically, the synthesis course involves two steps: (1) formation of amesostructured transition metal oxide solid mediated by surfactant in a basicaqueous solution; and (2) treatment of the solid product in an acidic organicsolvent containing the respective precursor from which the solid product wasproduced. The final material synthesized according to such a method isthermally stable and structurally mesoporous with high surface area anduniform pores arranged disorderedly.
