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)₂CHOH∶ALE volume ratio was equal to 0.5∶8∶40, 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.
