Abstract

A facile and shape-controlled crystallization process for preparing molybdenum oxide-based hybrid materials (MOBHMs) from peroxomolybdate solutions was proposed. The morphology of the MOBHMs could be effectively regulated by the assembly of polyethylene glycol (PEG), which acted as a mild reducing agent and a structure-directing agent. The effects of polymer concentration, reaction temperature, and time on the crystal phase and morphology of the MOBHMs were investigated in detail. It was found that the morphologies of amorphous products changed from sphere to a mixture of sphere and cube and then to cube with increased reaction temperature in the presence of 100 g L-1 of PEG. At 70 degrees C, monoclinic H2MoO5 with a ribbon shape was obtained in the absence of PEG. Moreover, increasing the polymer concentration resulted in a morphology transition from ribbon to sphere and then to cube. Correspondingly, phases transition occurred from triclinic MoO3 center dot H2O to amorphous products. Additionally, the phase and morphology of the as-prepared samples hardly changed with prolonged reaction time. A possible combination and growth mechanism has been proposed for the formation of the MOBHMs in aqueous solutions.
