Embodiment Construction

[0030] The present invention and its beneficial effects are further described below through the embodiments and accompanying drawings.

[0031] A new type of nanomaterial V 10 o 24 12H 2 The preparation method of O comprises the following steps,

[0032] 1. Preparation of sol

[0033] The sol was prepared by the sol-gel method, and the V 2 o 5 The powder and hydrogen peroxide were mixed at a molar ratio of 1:90, placed in an ice-water mixing bath at 0° C., and magnetically stirred for 1 hour to obtain a reddish-brown homogeneous sol. The sol was taken out from the ice-water mixed bath, left at room temperature for 30 minutes, and then boiled to form a wet gel while releasing a lot of heat and gas. The wet gel was sealed and stored at 30°C.

[0034] Second, the aging of the sol

[0035] The sol was stored in an oven at 30°C for 3 days to form a uniform gel.

[0036] 3. Preparation of sample V by solvent replacement and atmospheric pressure drying 10 o 24 12H 2 o

Abstract

The invention discloses a method for preparing a novel nano-material V10O24.12H2O. The method takes industrial vanadium pentoxide powders and peroxide as main raw materials, uses a sol-gel method, combines with a solvent replacement process and prepares a nano-porous material at normal pressures. The method comprises the following steps of: using the V2O5 powders and the peroxide to prepare the sol by a sol-gel method; sealing and storing the sol till gel is formed; ageing the gel and carrying out solvent replacing and drying at normal pressure. The method has the advantages of cheap and easily obtained raw materials, simple reaction process, moderate reaction conditions, etc. The method well makes up the shortcomings of preparing the V10O24.12H2O by the hydrolysis method and fusing method of organic vanadic salts, and leads the preparation of the material to tend to mature.

Description

technical field [0001] The invention belongs to the field of materials and relates to a method for preparing vanadium oxide materials. Background technique [0002] Energy crisis and environmental protection pressure are two severe challenges that mankind must face. The huge energy system established in the 20th century can no longer meet the requirements of the future society for an efficient, clean, economical and safe energy system. Therefore, the development of new energy And new energy materials are one of the key technologies that must be solved in this century, and also one of the most decisive technologies in the world economy. [0003] With the continuous increase in the demand for secondary chemical new energy and the improvement of environmental protection requirements, people are paying more and more attention to the development and application of low-pollution secondary chemical new energy. Lithium-ion battery is one of the most promising new chemical energy so...
