A method for low-temperature synthesis of h-moo3 microrods

Abstract

The invention relates to a method for synthetizing h-MoO3 at low temperature. The method comprises the following steps of adding (NH4)6Mo7O24.4H2O into deionized water and stirring so as to prepare a solution A; regulating the pH value of the solution A to be 0.5-3.0 so as to obtain a solution B; pouring the solution B into a four-neck round-bottom flask and putting the flask into a synthetizing extraction reactor integrating functions of microwave, ultraviolet and ultrasonic, after reaction, naturally cooling to room temperature, opening the synthetizing extraction reactor integrating functions of microwave, ultraviolet and ultrasonic, taking out the product, after washing by deionized water and absolute ethyl alcohol sequentially, drying in an electric heating vacuum drying oven so as to obtain the h-MoO3 micrometer crystal. According to the method, the synthetizing technology range of the h-MoO3 micrometer crystal is enlarged, the prepared h-MoO3 micrometer crystal has simple technology, the raw material is easy to obtain, the yield is high, the reaction period is short, and the cost is low; the obtained h-MoO3 micrometer rods grow completely, have high purity and good crystallinity, and are distributed uniformly; the method can be used for synthetizing h-MoO3 micrometer crystal on a large scale.
