Abstract:	TiO2 with photocatalytic activity under visible light was used as feedstock in Cold Gas Spray process. Spraying conditions were adjusted so as to mechanically embed the active particles into the substrate surface. The powder was also combined with ductile metallic powder in order to enhance the adhesion of the coating. Stainless steel cylinders were coated and placed in tubular reactors for their application in the degradation of different contaminants
