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
