Fabrication of Fuel Reforming Catalytic Coatings for Hydrogen Production by Cold Spray Technology
Commercial catalyst of CuO/ZnO/Al2O3 was used as feedstock to coating fabrication for hydrogen production through fuel reforming on aluminum plate. Microstructure and micro-region composition of the coatings were analyzed by SEM and EDX. It was found that the composition of feedstock and coating was basically the same; Bonding between the particles in the coating and the bonding between the coating and substrate was mainly belonged to mechanical bite and physical bonding; At low heating temperature in spraying, the coating presented applanation loosen cascade state of porous structure; Morphology of the coating influenced by heating temperature and fracture character of the particles; Methanol steam reforming reaction on the coating confirmed that cold spray technology can be successfully applied to fabrication of catalytic coating material.
