Plasma electrolytic oxidation layers as alternative supports for metallic catalysts used in oxidation reaction for environmental application

In order to reduce the impact of production processes on the environment, wastes can be modified by metallic supported catalysts (MSCs). One of the techniques in preparing supports for MSCs could be Plasma Electrolytic Oxidation (PEO) process used to produce a uniform, adhesive and porous layer on the surface of metals, including Ti as the layers which are carriers for catalysts. As a result, more diverse products in terms of shape and mechanical properties, especially in comparison with ceramic based catalysts, could be produced. In this review, application of the PEO process to the production of MSCs will be presented.

Automated summary

To reduce the environmental impact of production processes, metallic supported catalysts (MSCs) can modify wastes. One technique for preparing supports for MSCs is Plasma Electrolytic Oxidation (PEO) process, which creates a uniform, adhesive, and porous layer on metal surfaces, including titanium as the carrier for catalysts. This enables the production of more diverse products with various shapes and mechanical properties compared to ceramic based catalysts. This review presents the application of the PEO process in MSCs production.
