Description

technical field [0001] The invention belongs to the technical field of chemical synthesis equipment, and in particular relates to a nano catalyst synthesis device. Background technique [0002] Nano-photocatalyst is the nemesis of pollutants, and its mechanism of action is simply: nano-photocatalysts are excited to generate "electron-hole" pairs under the irradiation of light of a specific wavelength. This "electron-hole" pair and the surrounding water After the action of oxygen, it has a strong oxidation-reduction ability, which can directly decompose formaldehyde, benzene and other pollutants in the air into harmless and tasteless substances, and destroy the cell wall of bacteria, kill bacteria and decompose their silk screen Bacteria, thereby achieving the purpose of eliminating air pollution.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, composite nano-photocatalysts often have better catalytic effects; composite nano-photocatalysts can be synthesized through aqueous phase, which requires sufficient mixing of two or more metal precursors to form nano-clusters, and then mixed with sodium sulfide. Synthesize composite nano-photocatalysts under heating conditions; in actual synthesis work, some metal precursors are easily oxidized, resulting in the inability to synthesize highly active nano-photocatalysts; and the addition rate of metal precursors is uncontrollable during the synthesis process. The uneven mixing of precursors affects the formation of nanoclusters, thereby affecting the performance of nanophotocatalysts
