EFFECT OF PROCESSING TEMPERATURE ON THE PHOTOCATALYTIC ACTIVITY OF G-C3N4/MONTMORILLONITE COMPOSITES

Popis výsledku v původním jazyce

The aim of the present work was the preparation of photoactive composites of g-C3N4/MMT type. In this work, g-C3N4/MMT photocatalysts were prepared by thermal polycondensation of the mechanical mixture of melamine and MMT at different temperatures (450, 550, 600, 620, 650, and 700oC). Using wide range of analytical methods (X-ray diffraction, infrared spectroscopy, diffuse reflectance spectroscopy, and photoluminescence) a significant differences in crystalline structure, morphology, and optical properties between the prepared composites were found. Furthermore, composites prepared at 550-650 oC were tested for the photocatalytic decomposition of N2O. Photocatalytic experiments showed very similar activity of all samples synthesized at 550-650oC. The best photoactivity was exhibited by the sample prepared at the highest temperature (620oC and 650oC). The N2O conversion in presence of sample prepared at 620oC and 650oC was 45 % after 20 hours of UVA irradiation.
