One-pot synthesis of CdS/CeO2 heterojunction nanocomposite with tunable bandgap for the enhanced advanced oxidation process

Characterization

X-ray diffraction analysis

The structural properties and phase compositions of the synthesized nanocomposites with different molar ratios of CdS:CeO₂ were analyzed by X-ray diffraction analysis using Philips X’PERT with Cu-Kα radiation having a scan speed of 2°/min at 25 °C.

The X-ray diffraction pattern of the synthesized CdS/CeO₂ nanocomposites is represented in Fig. 3a. The peaks occurring at 2θ = 26.8_, 43.9, and 52.0, in the XRD spectrum of pristine CdS, could be indexed to the (111), (220), and (311), planes of hexagonal CdS (compared with JCPDS Card No…
