Embodiment 1

[0021] The preparation of molybdenum trioxide nanorod, its step is:

[0022] 1. Add 1gMoO 3 Dissolve the powder in 50ml of hydrogen peroxide (concentration: 30%), stir vigorously for 48 hours, then add 30ml of deionized water, stir and age for 48 hours to form a yellow transparent sol;

[0023] 2. Transfer the yellow transparent sol obtained in step 1 directly into a stainless steel reaction kettle with a polytetrafluoroethylene substrate, conduct a hydrothermal reaction at 180°C for 4 days, and cool naturally to room temperature to obtain a hydrothermal product;

[0024] 3. Wash and filter the hydrothermal product obtained in step 2 with absolute ethanol for 2 times, then with deionized water for 2 times, and dry at 80°C for 12 hours to obtain a light blue molybdenum trioxide laminated nanorod product.

[0025] The analysis and test of the obtained molybdenum trioxide product shows (see attached figure) that the synthesized product is in the shape of a short rod, the length ...

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.
