The invention belongs to catalysis material technical fields, specially Ti 3+ Auto-dope titanium dioxide optical catalyst and preparation method thereof.The present invention uses Ziegler-Natta, specific steps are as follows: butyl titanate, aluminium acetylacetonate, acetylacetone,2,4-pentanedione are dissolved in ethyl alcohol, by water-soluble in ethyl alcohol；Solution is stirred lower mixing by two kinds；It stands, obtains colloidal sol；Then colloidal sol is dried, obtains gel；Obtained gel is clayed into power；Then through high-temperature process, natural cooling is to get the Ti for arriving grey black 3+ ‑TiO 2 Product.Product of the present invention improves TiO in terms of light abstraction width, carrier mobility ability and interfacial reaction rate 3 2 Photo-catalysis capability, have good photocatalytic activity, can be applied to photocatalysis degradation organic contaminant, photolysis water hydrogen and photo-reduction CO 2 Field. |
