Enhanced photocatalytic activity of CaMoO4/g-C3N4 composites obtained via sonochemistry synthesis
Source abstract
Abstract
ABSTRACT Herein, CaMoO4-based g-C3N4 composites are successfully synthesized by the sonochemistry method. All samples present photocatalytic activity under UV-light irradiation by employing methylene blue (MB). The structural analysis is available through X-ray diffraction (XRD), Raman, and FTIR spectroscopies, which verified a scheelite-type tetragonal structure for CaMoO4 with slight distortion in [MoO4] clusters between samples and confirmation of g-C3N4 presence in the powder. FEG-SEM images reveal a higher formation of interfaces between CaMoO4 and g-C3N4 particles. Photoluminescence spectra are measured to study the photogenerated charge recombination process. Furthermore, the studies show that increased dosage of g-C3N4 onto the composite provides up to 95.1% of MB discoloration in 180 min, while CaMoO4 without g-C3N4 only provides 40.2%.
