Abstract

• Green synthesis of TiO2 nanoparticles was produced by Aloe Vera leaf. The structural properties of TiO2 nanoparticles were characterized by X- ray diffraction (XRD). The chemical properties of TiO2 nanoparticles were analyzed by Fourier Transform Infrared Spectroscopy (FTIR). The surface morphology and optical properties of TiO2 nanoparticles were characterized by Scanning Electron Microscopy (SEM) and Ultraviolent Spectroscope (UV-Vis) measurements. According to experiment result, the extraction of Aloe Vera leaf dyne solution was performed and employed as natural dyne sensitizer in DSSC.
