Paper Abstract

TiO2 nanoparticles (NPs) with high-photocatalysis properties both in ultraviolet and visible-light regions were synthesized via a simple sol-gel method, and an aloe leaf extract (ALE) was used as the cap. When the Ti(OC4H9)4∶(CH3)2CHOHALE volume ratio was equal to 0.5840, the reaction time was 6 h, and crystallization occurred at 80°C for 2 h, the TiO2NPs had been synthesized. XRD analysis showed that the structure of TiO2NPs without thermal treatment was anatase. Transmission electron microscopy images confirmed their average size, which was around 5 nm. The products showed an excellent photocatalytic property for methyl orange in the presence of UV and sunlight with the characterization of UV-vis. The photocatalytic activity was optimized by adjusting the amount of TiO2, the pH value, and the calcination temperature. Results indicated that ALE acted as a cap and nano-TiO2 could be synthesized without calcination.
