Abstract
Photocatalytic papers were fabricated from 13X zeolite based modified nano titanium dioxide (TiO2) for activation under visible light irradiation. Codoped nitrogen–iron nano titania (N–Fe–TiO2) sol was synthesized and supported on 13X zeolite powder at different fractions and added to the paper pulp suspension. The products were characterized by XRD, SEM, EDS, and UV–vis diffuse reflectance spectra analysis. The photodegradation activity of the papers was investigated under batch conditions for the removal of acetaldehyde in air as an indoor pollutant under visible light irradiation. The results revealed that the fabricated paper was active under visible light irradiation and the photocatalytic efficiency of zeolite-based N–Fe–TiO2 paper was 2.1-fold that of unmodified pure TiO2 containing paper.
