Enhanced Photocatalytic Activity of WO3 Nanoparticles Loaded with Carbon
AIP Conf. Proc. 2026, 2026, 020013 (2018)

Enhanced photocatalytic activity of WO3 was attempted by carbon nanodots (C-dots) loading. C-dots were
prepared using citric acid and urea for enhancing photocatalytic activity of WO3. Physicochemical character of C-dots
was studied by fluorescence spectrophotometry and for the modified WO3, evaluation was studied by using x-ray
diffraction (XRD) and scanning electron microscope (SEM). Effect of varied citric acid: urea ratio to photocatalytic
activity was evaluated in methylene blue photodegradation. Increasing photocatalytic activity was achived by higher
intensity in blue color range that obtained by higher urea molar ratio. Kinetics of reaction obey pseudo-first order and
pseudo-second order reaction. Reaction reached 80% MB degradation for an hour treatment for 50mM of methylene blue
solution.
