Abstract

DC60 Products, which include a 3D grid material, are coated with a particle support, and the coating may be coated by an electro-swim coating process. In order to apply the particle coating on the surface or enter the inner part of the three-dimensional network material in a significant manner, the particle is the catalyst or the catalyst reactant. Or a catalyst aid, which gives a catalyst structure that the catalyst may It is rescued as a coating on the inside and on the outside of the network material. Three dimensions with large cavitation volumes As a result, the margins may have been reduced. By controlling the separation of the electric field lines during the coating process. Larger particles may also be given an electro-swim coating on the product by Using smaller particles that act as a "glue", the product, which consists of a 3D grid material, is coated with a particle support.
