A kind of preparation device for nano precious metal catalyst and preparation method thereof

Abstract

The invention discloses a preparation device for nano-precious metal catalysts and a preparation method thereof, comprising a low-temperature drying box, a storage box is welded on one side surface of the low-temperature drying box, and the bottom of the storage box is rotatably connected with a A connecting shaft, the middle part of the connecting shaft is sleeved with a working plate, the shape of the working plate is L-shaped, the inner side of the L-shaped working plate is equidistantly welded with a connecting block, and the end surface of the connecting block is glued with a receiving sleeve, A beaker is installed inside the containment cover. The present invention is scientific and reasonable, safe and convenient to use. Use a measuring cylinder to measure an appropriate amount of reaction solution, put it into the beaker in the containment cover for reaction, and finally use the filter assembly to clean and filter to complete the entire preparation process. Realize the separate use of the preparation equipment, cover the work plate at the same time, insert the L-shaped insert into the fixing sleeve to fix the work plate, and store the preparation parts separately, which is convenient for the next use and effectively prevents dust.

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...
