摘要
Despite the proven efficiency of heterogeneous photocatalysis using immobilized catalysts, this process lacks integration with the industry due to limitations on mass and photon transfer. The current study aimed to go up against this scenario by applying for the first time a Kenics (R) static mixer as catalyst support for heterogeneous photocatalysis in tubular reactors. Stainless steel Kenics (R) static mixers coated with TiO2 or Fe2O3 photocatalyst were assembled in a borosilicate tube coupled to a compound parabolic collector (CPC) and applied to the degradation of the antibiotic oxytetracycline (OTC) in aqueous solution. The use of the Kenics (R) static mixer provided intense mixing even under laminar flow, and, beyond that, the use of sunlight and a CPC ensured that the entire photocatalyst surface area was receiving front side illumination.
