Embodiment 1

[0025] Nafion / TiO 2 Preparation of hybrid thin film plates:

[0026] 1) Take 100 g of Nafion solution with a mass concentration of 5%, add 100 g of isopropanol dropwise to the solution, stir evenly, add 2 g of Ncepowd HYD-20 titanium dioxide powder to the solution, and mix the solution fully and evenly to obtain titanium dioxide Mix the carrier fluid.

[0027] 2) Use 5g of p-hydroxybenzenesulfonic acid as a hardening agent, and then take 50g of polydimethylsiloxane stock solution, and fully stir and mix the two. Add the mixed solution of dimethyl siloxane and hardener dropwise into the profile frame, put the profile frame containing the mixed solution of dimethyl siloxane and hardener into a vacuum glass dish, and evacuate it with a vacuum pump for 30 minutes. After removing the air bubbles in the mixed solution, the dimethylsiloxane stock solution profile is prepared.

[0028] 3) Select a charged adhesive glass slide with a positive charge on the surface (for example, "803...

Abstract

The invention relates to environment sewage treatment, and concretely relates to a film plate used for photocatalytic degradation of phenol pollutants in sewage. The film plate is Nafion / TiO2 hybrid film with a size being 5-10 mm loaded at charged adherence slide glass; and the Nafion / TiO2 hybrid film contains nano-level TiO2 particles. The Nafion is used as a carrier and a modifier, the TiO2 is loaded in the hybrid film, and is adhered to the charged slide glass to obtain the film plate. The film plate can be used as a photocatalysis material for degrading the phenol pollutants in sewage, iscapable of filtering, adsorbing and degrading the phenol pollutants in the sewage, and has a wide purpose.

Description

technical field [0001] The invention relates to environmental sewage treatment, in particular to a film plate used for photodegradation and catalysis of phenol pollutants in sewage. Background technique [0002] The hybrid thin film combining nano-organic / inorganic materials is a homogeneous multi-phase material, in which at least one phase is a nano-scale material, and the nano-phase and other phase materials are compounded and hybridized through physical or chemical interactions. This hybrid thin film has significantly different characteristics compared with traditional composite materials in terms of structure and performance. [0003] TiO 2 It is often used in paint, ink, plastic, rubber, paper, chemical fiber and other industries, and can also be used as welding rod material. Nanoscale Ultrafine TiO 2 (10-50nm) generally has semiconductor properties, and at the same time has high stability, high transparency, high activity and high dispersibility, and has no toxicity...
