[0019] Ta-POM-1 / TiO 2 Preparation of composite photocatalytic materials

[0020] 1. The precursor contains tantalum polyacid H 4 K 8 Na 8 [P 8 W 60 Ta 12 (H 2 O) 4 (OH) 8 O 236 ]·NH 2 O, labeled Ta-POM-1, synthesized according to literature: J. Am. Chem. Soc., 2012, 134, 19716−19721.

[0021] 2. Dissolve 10 mL of isopropyl titanate in 30 mL of isopropanol to obtain solution A; dissolve 1 g of tantalum-containing polyacid Ta-POM-1 in 2 mL of deionized water to obtain solution B; drop solution B under ultrasonic conditions Add to solution A and continue ultrasonic treatment until gel is formed after the addition is complete. After aging for 12 hours, put the gel in an autoclave at a heating rate of 2°C / min to 150°C for 12 hours, and cool to room temperature After that, the sample was filtered and washed with deionized water at 80°C for several times until the ultraviolet-visible absorption spectrum of the eluent had no absorption peak of polyacid, and then the obtaine...

Abstract

The invention discloses a visible light driven photocatalysis hydrogen production catalyst as well as a preparation method and application thereof. According to the technical scheme of the invention, tetraisopropyl titanate and tantalum-containing polyacid Ta-POMs-1 are adopted as precursors, the photocatalysis hydrogen production catalyst Ta-POM-1/TiO2 is prepared by using a sol-gel method; and by optimizing and selecting types and amounts of dye molecules, types and amounts of sacrifice catalysts and amounts of the catalyst, the reaction conditions of catalysis hydrogen production with visible light, of the catalyst, can be optimized. Compared with parent TiO2 and POMs, a prepared Ta-POM-1/TiO2 composite photocatalysis material is relatively good in visible light absorption and relatively high in photocatalysis hydrogen production activity, so that the visible light driven photocatalysis hydrogen production catalyst is relatively good in application prospect in the field of photocatalysis.

Description

technical field [0001] The invention belongs to the technical field of synthesis of composite photocatalytic materials, and in particular relates to a photocatalytic hydrogen production catalyst driven by visible light and its preparation method and application. Background technique [0002] Since entering the 21st century, while enjoying the comfort and convenience brought by the development of science and technology, human beings are facing two major survival crises: the depletion of fossil energy such as coal and oil; the gradual deterioration of the living environment, and the burning of fossil resources. released CO 2 , SO 2 And other harmful gases have brought many environmental problems such as the greenhouse effect and acid rain. Finding clean and renewable energy is an urgent need to achieve sustainable development and improve the quality of human life. The thermal efficiency of hydrogen is three times that of ordinary gasoline, and the combustion products have n...
