Abstract

The present invention provides one kind of nanometer MoO3 stick and its preparation process. The laminated nanometer MoO3 stick in orthorhombic system has length 1-10 microns, 3-9 laminated MoO3 layers, thickness 50-200 nm and width 60-120 nm. The preparation process includes dissolving molybdenum oxide or molybdate in hydrogen peroxide solution via intense stirring for 30-50 hr to form sol, transferring the sol into stainless steel reaction tank with PTFE lining, hydrothermal treatment at 150-180 deg.c for 4-6 days, naturally cooling to room temperature to obtain hydrothermal product, anhydrous ethyl alcohol washing and water washing, and drying. The preparation process is simple, high in reproducibility, controllable, and environment friendly. The prepared nanometer MoO3 stick has high surface activity and may be filmed via brushing or spraying and prepared into electrochemical and optical devices directly or after being mixed with other superfine powder.

Example Embodiment

[0020] Example 1:
[0021] The steps for preparing molybdenum trioxide nanorods are:
[0022] 1. Put 1gMoO 3 The powder was dissolved in 50ml hydrogen peroxide (30% concentration), stirred vigorously for 48 hours, then added 30ml deionized water, stirred and aged for 48 hours to form a yellow transparent sol;
[0023] 2. The yellow transparent sol obtained in step 1 is directly transferred into a stainless steel reaction kettle with a polytetrafluoroethylene substrate, hydrothermally reacted at 180°C for 4 days, and naturally cooled to room temperature to obtain a hydrothermal product;
[0024] 3. The hydrothermal product obtained in step 2 is washed and filtered with absolute ethanol twice, then washed and filtered with deionized water twice, and dried at 80° C. for 12 hours to obtain a light blue molybdenum trioxide laminated nanorod product.
[0025] The obtained molybdenum trioxide product analysis test shows (see the attached picture) that the synthesized product is in the shape of short rods, the length of the nanorods is 1-10μm, and each nanorod is composed of 3-9 molybdenum trioxide layers superimposed. It is 50-200nm and the width is 60-120nm.
[0026]
[0027] According to the above experimental parameters, refer to the method of Example 1 to obtain the molybdenum trioxide laminated nanorod product.
