Abstract
The invention provides a preparation method used for loading active carbon with titanium oxide. According to the preparation method, fiber cloth is taken as a template, and active carbon fabric loaded with titanium oxide is obtained via processes such as swelling, dipping, and sintering. Advantages of the preparation method are that: the obtained fiber cloth possesses both high catalytic activity of titanium oxide and high adsorption performance of active carbon, and possesses higher water processing efficiency; peeling of titanium oxide from active carbon is difficult to be caused, and the fiber cloth can be recycled. The active carbon fabric loaded with titanium oxide can be used as a photocatalysis material of sewage processing, and as an air sterilization and deodorizing material.
Description
(1) technical field
What the present invention relates to is that a kind of titanium oxide supports the preparation method in activated carbon felt, specifically relate to a kind of preparation titanium oxide is supported on activated carbon felt, and have the presoma method for transformation of good photo-catalysis capability, belong to inorfil and catalysis material field.
(2) background technology
A kind of important inorganic functional material of titanium oxide, is widely used in modern industry, agricultural, national defence and scientific and technical numerous areas.Within 1972, find first that titania surface can be by organic matter in photocatalysis last decomposition water, its as catalysis material in water treatment, purify air, the aspect such as sterilization, deodorizing is widely used.Lot of documents report is thought: titanium oxide is a kind of good catalysis material, it almost can degradation water in or airborne organic matter, the organic matter of the low concentration of especially thoroughly degrading, and trade effluent belongs to low strength range just.Due to titanium oxide chemically stable, nontoxicity, raw material is cheap, and photocatalytic activity advantages of higher is considered to the most possible ideal material for industrialization sewage disposal.The main method of preparing at present titanium oxide has sol-gal process, vapour deposition process, hydrothermal synthesis method etc., and the form of titanium oxide is also substantially with film, fiber, powder or be deposited on other material surfaces.Each defectiveness of these methods, they or complex process, cost is high, or recycling is more difficult.Wherein a lot of scholars, by adsorb nano titania or colloidal sol on activated carbon or activated carbon fiber, overcome a difficult problem for recovery, but that titanium oxide prepared by this method is combined with matrix is insecure, and titanium oxide easily peels off from matrix; Also have scholar that titanium oxide is prepared into fabric shape, its catalytic efficiency is between nano particle and thin film of titanium oxide.What this method adopted is presoma conversion preparation method, and titanium oxide is supported on activated carbon felt securely, and technique is simple, with low cost, and it is convenient to reclaim, and takes into account the highlight catalytic active of titanium oxide and the high adsorption of high activity charcoal.
(3) summary of the invention
The invention provides a kind of titanium oxide and support the preparation method in activated carbon felt, particularly provide a kind of presoma method for transformation of preparing the activated carbon felt that supports titanium oxide, to make up the deficiencies in the prior art; The present invention is a kind of method that supports titanium oxide of novelty, has solved the problem that existing titania meterial catalytic efficiency is low and reclaim.
The invention provides a kind of titanium oxide and support the preparation method in activated carbon felt, its sintering process is that fiber cloth after dipping is put into atmosphere furnace, under air or nitrogen or ammonia atmosphere, with the heating rates of 5～15 ℃/h, rise to certain temperature of 250～375 ℃, be incubated after 2～8 hours, naturally cooling, obtain the activated carbon felt that supports titanium oxide.
The invention provides a kind of titanium oxide and support the preparation method in activated carbon felt, have and support firmly, technique is simple, with low cost, reclaims the features such as convenient, easy commercialization, can be widely used in organic degraded and deodorization and sterilization etc. in air, water.
