Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0023] Such as figure 1 , figure 2 , image 3 , first, a certain amount of zinc acetate Zn(Ac) 2 and cadmium acetate Cd(Ac) 2 Add the material into the material mixing chamber 26 through the feed port 2 in sequence, then add deionized water through the feed port 2 according to a certain proportion, and fully dissolve the material under the stirring of the agitator a3. After complete dispersion, control the manual control valve h22, The precursor mixture is introduced into the autoclave 20 through the liquid outlet a23. Similarly, the sodium hydroxide NaOH solution and the thioacetamide solution are uniformly dispersed and then slowly transferred to the autoclave. Since the dissolution of NaOH will release a large amount of heat, the circulating cooling water a25 needs to be passed throu...

Abstract

The invention provides a batch preparation device and a preparation method of a catalyst by synthesis of a hydrothermal method. The device comprises a material mixing unit, a high-temperature high-pressure reaction unit, a waste gas absorption unit and an ultra-filtration unit. At present, a single-batch synthesized photocatalyst is in a couple of gram scale to dozens of gram scale, and cannot be applied to large-scale industrial production, while based on experimental researches, the preparation method is designed by analyzing and comparing industrial practice processes, the synthesized catalyst has excellent photocatalytic activity, and the single-batch yield of the catalyst is increased by hundreds of times, reaching nearly 1000 grams. The preparation device and the preparation method realize important practice of photocatalysts from the laboratory stage to industrialization, and the blank in the field is filled up.

Description

technical field [0001] The invention relates to the technical field of photocatalytic decomposition of water to produce hydrogen, in particular to a batch preparation device and preparation method of a hydrothermal synthesis catalyst, which is an important practice for realizing industrialization. Background technique [0002] "Energy security is an overall and strategic issue related to the country's economic and social development. It is crucial to the country's prosperity and development, improvement of people's lives, and long-term social stability." New energy, renewable energy multi-wheel-driven energy supply system", it is necessary to further strengthen the research and development of new energy, renewable energy. Using photocatalytic reactions to convert solar energy into hydrogen energy and establishing a large-scale new "solar-hydrogen energy" system can not only solve the problems and deficiencies in the utilization of both, but also facilitate the establishment ...
