In this paper, ZnO nanoparticles are synthesized by biosynthesis method using aloe vera gel/leaf aqueous extract. The obtained nanoparticles are characterized using IR and XRD. The IR results show the absorption band of Zn–O at 498 cm−1, while the powder XRD pattern confirms the hexagonal wurtzite-type structure with particles' size of 35.01 nm. ZnO nanoparticles are used as catalysts for degradation of methylene blue using hydrogen peroxide as an oxidant. The catalytic activity is calculated.

KEY WORDS: ZnO nanoparticles, plant extract, aloe vera gel, methylene blue degradation
