AACVD system and protocol to fabricate CuO and Co(3)O(4) nanostructured coatings for application as selective absorbent materials

In the present work, an aerosol-assisted CVD (AACVD) system is described, together with a representative example of the synthesis of nanostructured coatings, which is an attractive alternative to being implemented at the industrial level. The semi-automated AACVD system synthesizes thin films or coatings of nanostructured materials, mainly metal oxides, and noble metals. Its main components, as well as its operation, are presented here. This simple AACVD method makes it possible to produce the coatings at relatively low temperatures and in a single step. Finally, the synthesis of CuO and Co(3)O(4) nanostructured coatings deposited on stainless steel substrates is reported, which are excellent candidates for use as selective absorbent materials. The CuO and Co(3)O(4) a).. An AACVD System for depositing thin films and coatings designed and entirely fabricated at the Centro de Investigación en Materiales Avanzados, S.C. b).. A low temperature (350 °C) synthesis protocol to obtain CuO and Co(3)O(4) nanostructured coatings on stainless steel substrates. c).. The CuO and Co(3)O(4) coatings presented the optimum characteristics to be considered selective absorbent materials.
