【Abstract】 The molybdovanadophosphate nanoparticles with Dawson structure (NH 4 ) 8 P 2 Mo 16 V 2 O 62 ·7H 2 O were synthesized by solid state reaction at room temperature and characterized by elemental analysis, IR, XRD, TEM, TG DTA and BET techniques. The nanoparticles are found still to exhibite Dawson structure with average size being 22 nm and BET area 167 m 2 /g. They are stable at temperature <441 ℃.更多还原
