Abstract

This research highlights the enhanced solar-driven photocatalytic activity of a CeO2@g-C3N4 nanocomposite, fabricated through a straightforward and economical co-precipitation approach. Physico-chemical properties were analyzed through various studies such as X-ray diffraction (XRD), Transmission electron microscopy (TEM), Fourier Transform Infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and Ultraviolet visible spectroscopy (UV–Vis). The photocatalytic efficiency of nanocomposite was evaluated against azo dyes. The particle size was found to be ~ 15 nm from XRD and in the range of ~ 10 nm from TEM estimated using ImageJ software. Observed band gap energy for CeO2@g-C3N4 nanocomposite was ~ 2.7 eV calculated from Tauc plot using UV-DRS analysis. Addition of g-C3N4 was confirmed by survey spectra of XPS analysis. The valence spin with binding energy were studied for the prepared CeO2@g-C3N4 nanocomposite. The CeO2@g-C3N4 acted as a supreme photocatalyst to reduce two different dyes such as methylene blue and Congo red with higher efficiency of 84% and 76% at 70 min under solar light excitation. The appreciable result was credited to the CeO2@g-C3N4 heterostructure matching energy levels, which promoted the movement and decrease the recombination rate of photo induced charge carriers.
