Preparation device and preparation method for nano noble metal catalyst

Abstract

The invention discloses a preparation device and preparation method for a nano noble metal catalyst. The preparation device comprises a low-temperature drying box; a storage box body is welded on a side surface of the low-temperature drying box; a connecting shaft is in penetrating rotating connection with the bottom of the storage box body; the middle of the connecting shaft is connected with a working plate in a sleeve mode; the working plate is in an L shape; connecting blocks are welded on the L-shaped inner side of the working plate at equal intervals; the end face of each connecting block is bonded with a containing sleeve; and each containing sleeve is internally provided with a beaker. The device is scientific and reasonable in structure and is safe and convenient to use. Proper amounts of reaction solutions are measured by a measuring cylinder; then the reaction solution is put into beakers in the containing sleeves for reaction; and finally cleaning and filtering are carriedout by using a filtering assembly, so that the whole preparation process is completed, and independent use of the preparation device is realized. Meanwhile, the working plate is covered, and an L-shaped inserting strip is inserted into a fixing sleeve to fix the working plate, so that preparation components can be separately stored, use for the next time can be facilitated, and an effective dust prevention effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of noble metal catalysts, in particular to a preparation device and a preparation method for nanometer noble metal catalysts. Background technique [0002] Noble metal catalyst is a noble metal material that can change the speed of chemical reactions without participating in the final product of the reaction. Almost all noble metals can be used as catalysts. Their d electron orbitals are not filled, the surface is easy to adsorb reactants, and the strength is moderate. , which is conducive to the formation of intermediate "active compounds", has high catalytic activity, and also has comprehensive excellent properties such as high temperature resistance, oxidation resistance, and corrosion resistance, and has become the most important catalyst material. The commonly used nano-precious metal catalysts are prepared by chemical reduction , in water or organic solution, using a suitable reducing agent to reduce t...
