DEVELOPING WAYS TO INCREASE THE SPECIFIC SURFACE OF THE METAL CATALYST AND CARRIER FOR THEM
TALKING POINTS:

Development of the chemical and petrochemical industry is impossible without the creation of new production technologies of raw materials and products. To a large degree, the success in this field is defined broadly using catalysts, particularly copper containing catalysts. Typically to create catalysts used as the carrier an oxide ceramic or a porous substrate. In our opinion, promising all-metal nanocatalysts can be made of copper and its oxides with high surface area. Such catalysts have many advantages, but one major drawback - low specific surface area.

In this paper, we propose a number of ways to increase the specific surface area of copper-containing catalysts and supports for them. In particular, to increase the specific surface of the carrier it is possible by heat treatment in oxygen-containing environment, and increase the surface area can nanocatalyst by growing by electrodeposition on the carrier:

- layers of copper nanoparticles;

- icosahedral small particles (ISP) of copper and subsequent by etching;

- ISP copper and subsequent heat treatment in a vacuum;

- pentagonal copper crystals and their subsequent heat treatment in oxygen-containing medium;

- crystals, the copper layers and coatings having been in the initial state after the electrodeposition developed surface.
