摘要：
Control of the size, shape, and structure of mesoporous transition metal oxide materials is important in their correlations with corresponding optoelectronic and photocatalytic properties. Highly ordered cubic phases of mixed-valent mesoporous molybdenum oxides have been prepared by the reduction and decomposition of aqueous molybdenum precursor solution in the presence of poly(ethylene oxide) under ultrasonic irradiation. Large-scale uniform molybdenum oxide particles with well-defined crystal-like morphologies (ball-like, rhombic dodecahedral, and cubic shapes) were synthesized and found to be controllable by modifying the molecular chain length of the polymeric additive. Molybdenum oxides with an average oxidation state of 4.8 form a cubic lattice of open mesoporous structures. Copyright © 2005 American Chemical Society.
