The preparation of tellurium dioxide (TeO2) nanoparticles in a mild condition had been studied. The acid medium, such as gallic acid or acetum was used to prepare the TeO2 nanoparticles at room temperature. The functions of acids were investigated by Nano-ZS, TEM, SEM, FTIR, Raman spectra and XRD. The results showed that the modification and modulation of gallic acid on the TeO2 nanoparticles were stronger than that of acetum. The TeO2 nanoparticles prepared in gallic acid were the orthorhombic phase β-TeO2 spheres in the range of 30–200 nm. The TeO2 nanoparticles prepared in acetum were the tetragonal phase α-TeO2 irregular flakes in the range of 40–400 nm.
