The technology consisted of a continuous gas flow phase reactor containing a 3D printed PET support impregnated with TiO2 as photocatalyst. The 3D impregnated supports were characterized by diffuse reflectance spectrometry and SEM/EDS. The effect of several key-factors on the removal capacity were studied: type of PET filament (native, BPET vs glycol-modified, PETG), type of TiO2 (P-25 vs Hombikat UV-100), UV-light source (LED vs tubular lamps) and number of deposited TiO2 layers. The highest NO and NOx removal were achieved by only one layer of Hombikat UV-100 over PETG supports, irradiating from both sides of the flat reactor with two sets of black light lamps. This work demonstrate that 3D printing is a reliable and powerful technique for fabrication of photocatalytic reactive supports.pdfengopenAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/Attribution-NonCommercial-NoDerivatives 4.0 InternacionalTiO23D printingheterogeneous photocatalysisNOxinfo:eu-repo/semantics/conferenceObjectAtribución
