THERMOSENSITIVE TRIBLOCK COPOLYMER TEMPLATED SYNTHESIS OF Pt-Cu SUPPORTED ON TiO_2: INVESTIGATION OF THEIR CATALYTIC ACTIVITY FOR CO OXIDATION REACTION

摘要

Pt-Cu/TiO_2 catalysts were prepared by two reductive deposition methods, using a thermosensitive triblock copolymer as template agent. The prepared catalysts were characterized using X-Ray Diffraction, SEM microscopy, EDX, UV-Vis Diffuse Reflectance Spectroscopy and CO pulse chemisorption measurements. The CO oxidation over Pt-Cu/TiO_2 materials was evaluated in order to investigate the impact of preparation methods on the catalytic performances.
