Abstract: Disclosed are molybdenum trioxide with a novel molecular structure and a chiral octahedral crystal phase structure, octamolybdate of the molybdenum trioxide and a preparation method of the octamolybdate. A molecular formula of ?-MoO3 with the novel molecular structure and the chiral octahedral crystal phase structure is Mo8O24, and the generated nano-molybdate based on the octamolybdate is a new species, so that a new member is added to inorganic salt chemical industry, and an application of the nano-molybdate changes all aspects of daily life of people, for example, the nano-molybdate having a disinfection function and insoluble in water is used in agricultural crop production and quality improvement, freshwater aquaculture and mariculture, sanitary disinfection, various anti-microbial and anti-tumor activities, batteries and various energy storages, semi-conductors, anti-biochemical weapons, intelligent materials and other aspects.

Abstract: A production device, method and application of nano-sized zinc molybdate. The device includes a double-cone mixer; an elevator is obliquely provided at a bottom of a discharge port of the double-cone mixer; a rear end of the elevator is located above a feeder; the feeder is connected to one end of an electric heating converter, an other end of the electric heating converter is connected to a finished product bin; a top of the finished product bin is provided with an atomizing nozzle for adding nanomaterial dispersant; the atomizing nozzle is connected to a syringe pump by pipeline. High-purity nano-sized molybdenum trioxide and nano-sized zinc oxide are adopted to synthesize nano-sized zinc molybdate in an electric heating converter. The nano-sized zinc molybdate prepared by the device and method can be used for treatment of African swine fever virus, coronavirus, and AIDS phase I, Ebola, dengue fever, polio viruses.

Abstract: A device and a method for producing high-purity nano molybdenum trioxide are provided. The device comprises a raw material bin (1), a feeding machine (2), a subliming furnace (7), a first vent tube (24), a second vent tube (25), a spraying device (23) and a filtering assembly. The sublimated molybdenum trioxide is cooled with clean and dehumidified air so as to finally obtain the nano molybdenum trioxide, and the recycling mode is reliable, pollution-free and high in efficiency.
