Application of nano molybdenum trioxide in thermal storage and photocatalysis

Abstract The thermal energy storage (TES) in phase change materials (PCMs) plays an important role in energy management systems. Paraffin has found wide range of applications as a PCM due to its unique thermal and physical properties. The present study reports about the synthesis of MoO3 nanomaterials using chemical method. MoO3 nanomaterial was diffused into paraffin wax in 0.5, 1, 1.5, and 2 weight percentages and thermal analysis was conducted. It was observed that 1.5 wt % doped PCM showed best enhancement in thermal performance with 20.28% and 35.71% improvement in heating and cooling cycles. The photocatalytic activity of synthesized nanocomposite was also evaluated by degradation of methylene dye under visible light irradiation. The photocatalytic degradation effectiveness of as synthesized nanocomposites has showed high photodegradation efficiency (93.83 %) of methylene blue under visible light radiation.
