Abstract: Hexagonal molybdenum oxide (h-MoO3) nano- and microrods were successfully synthesized by refluxing of (NH4)6Mo 7O24?4H2O solutions with the pH 1 at 90?C for 1, 3, 5, and 7 h and were further transformed into orthorhombic molybdenum oxide (?-MoO3) microplates by calcination at 450?C for 6 h. These selected products were used to determine the degradation of methylene blue dye under 35 W xenon lamp for 0-180 min, due to the photocatalysis and photosensitization processes. In this research, catalytic activity of the metastable h-MoO3 has higher efficiency than that of the thermodynamically stable ?-MoO3. Their phase and morphology transformation was also explained according to the experimental results. ? 2013 Pannipa Wongkrua et al.
