Description
Technical field
The present invention relates to a kind of foamed nickel supported TiO
2the preparation method of photochemical catalyst, belongs to the preparation method field of environment-friendly materials preparation.
Background technology
Photocatalytic method is the novel modern water technology that 20 century 70s grow up, compared with its pollutant physical adsorption with traditional water treatment and filtration method, have that technique is simple, cost is lower, great majority can be made at normal temperatures and pressures or can not to be difficult to biodegradable toxic organic compound oxidation Decomposition, thorough mineralising.Due to titanium dioxide there is chemical resistance and photoetch, nontoxic and catalytic activity is high, the advantage such as inexpensive and study at most, but considerable research carries out in suspension system, owing to there is catalyst separation and reclaiming difficulty, cost is too high and limit its application in practice, can only as a kind of laboratory Journal of Sex Research.
Therefore, the TiO that a kind of technique catalyst performance that is simple, preparation is good and be beneficial to recovery, reuse is studied
2the preparation method of photochemical catalyst has a good application prospect.
Summary of the invention
The present invention aims to provide the TiO that a kind of technique catalyst performance that is simple, preparation is good and be beneficial to recovery, reuse
2the preparation method of photochemical catalyst.
Foamed nickel supported TiO of the present invention
2the preparation method of photochemical catalyst, comprises the following steps:
Sol-gel process is adopted to prepare nano-TiO
2, the wet gel of formation is dry at 60 DEG C, and the xerogel obtained is constant temperature calcining 3h at 400 DEG C, with stove cooling, and obtained TiO
2powder, by TiO
2powder is dissolved in deionized water, disperses about 20min with sonic oscillation, then adopts the method for electrophoretic deposition by TiO
2powder deposits on carrier nickel screen, at certain temperature sintering, namely obtains foamed nickel supported TiO
2photochemical catalyst.
Preferably, carrier nickel screen of the present invention is porosity is more than 95% foam nickel screen.
Preferred, sintering temperature of the present invention is 600 DEG C, and sintering time is 2h.
Preparation method of the present invention, using the nickel foam of high porosity as catalyst carrier, due to TiO
2a kind of n-type semiconductor, in a solvent after dispersion, TiO under electric field action
2ultra micron can move to negative pole, so adopt the method for electrophoretic deposition by TiO
2powder deposits on carrier nickel screen, and sintering curing obtains product.According to carrier nickel screen to TiO
2loading can control the electrophoretic deposition time, the loading required with satisfied difference.After tested, prepared foamed nickel supported TiO
2photochemical catalyst uses does not have obscission tens times, and due to preparation method simple, and carrier adopts nickel foam (porosity is 95%), overcomes because of TiO
2solidification and catalytic activity reduce problem, industrially can be on the actual application.
Foamed nickel supported TiO of the present invention
2the preparation method of photochemical catalyst, has technique catalyst performance that is simple, preparation good, and is beneficial to recovery and recycling, and the application through industrial reality shows stable in catalytic performance, reliably, can reuse and be convenient to reclaim, can be widely used in industry.
