Azobenzene has attracted substantial attention as a photoswitchable molecule due to its applications range from energy and data storage to biomedical applications. This work reports a new type of thin-film based on azobenzene derivative anchored to Cerium oxide nanoparticles CeO2 NPs for photoswitching applications. The trans - cis isomerization and reverse isomerization occurs by UV-light exposure and thermal relaxation process, respectively. The photoisomerization and reverse isomerization kinetics for CeO2 NPs-MR thin films are studied, investigated, and analyzed using UV-Vis absorbance spectra, FTIR spectroscopy, XRD, and scanning electron microscopy (SEM), in addition to differential scanning calorimetry (DSC) measurement to study the energy storage capacity. The results found that anchoring azobenzene to CeO2 NPs is successful in multi-source storage of solar energy applications.
