Beta silicomolibdic acid/silica (β-SMA, a metastable form of silicomolybdic acid – H4SiMo12O40) forms by the impregnation of fumed silica into molybdenum solution obtained by hydrolyzation of MoO2Cl2. β-SMA/silica is found to be stable up to 300 °C after calcination for 1 h due to the existence of an interlayer MoO3 between silica surface and β-SMA. Structures of molybdenum species in the preparation process (including precursor solution) were analyzed by Raman spectroscopy and XRD.
