Description:
This work is related to the subject Clean Energy". Dimethoxymethane (DMM) is a suitable H2 storage material for mobile application due to its high H2 content and non-toxicity. It was found that DMM can be 100% reformed to produce H2 on a complex catalyst composed of an acid component such as Nb2O5 or niobium phosphate (NbP) combined with CuZnO/Al2O3 catalyst. Moreover, V2O5/NbP and V2O5-TiO2-SO42- catalysts were prepared and evaluated in the reaction of selective oxidation of methanol to DMM. The surface acidic and redox properties of V2O5-TiO2-SO42-were correlated to the reactive performance of the catalysts. The adsorption properties of Nb2O5 and NbP used in methanol dehydration reaction were also studied.
