The preparation method of visible-light response type cagelike structure vanadic acid copper hydrate photochemical catalyst

The invention provides a kind of preparation method of visible-light response type cagelike structure vanadic acid copper hydrate photochemical catalyst, NH is weighed 4 VO 3 Solid, is dissolved in deionized water, obtains NH 4 VO 3 The aqueous solution；Weigh Cu (NO 3 ) 2 ·3H 2 O solids, are dissolved in above-mentioned NH 4 VO 3 In the aqueous solution；Transfer the solution into autoclave, then reactor is placed in high temperature drying case；Reaction is cooled to room temperature after terminating, and uses multiplex vavuum pump of circulating water type filtered sample, with the abundant washing and filtering of deionized water, is dried overnight；Fully dried sample is ground, the visible-light response type cagelike structure vanadic acid copper hydrate photochemical catalyst of hydro-thermal method preparation is obtained.Photochemical catalyst prepared by the present invention can be used under visible ray decompose aquatic products oxygen as regenerative agent, and its oxygen-producing amount is significantly larger than other known at present regenerative agents.Preparation method of the present invention is simple, and cost is low, and photocatalysis performance is excellent, can be applied to the fields such as energy conversion and environmental improvement.
