【 摘 要 】

Titanium dioxide/magnetite nanocomposites become important materials due to their sophisticated potential applications regarding their significant roles in medical science. In this work, we reported the preparation of the titanium dioxide/magnetite nanocomposites prepared using a sol-gel method. The natural sand was explored as an important raw material to prepare the sample. Based on the structural characterizations, the sample size in nanometric ranged of 7.8 nm with amorphous and crystalline phases for titanium dioxide and magnetite, respectively. The vibrational characters of the samples were overlapped originating from Fe-O and Ti-O on the wavenumber ranged between 500-700 cm-1. Microscopy investigation showed that the sample agglomerated in a 3-dimensional fractal dimension as a spherical shape with the size of 34.8 nm. Interestingly, the samples had the optical band gap value of 2.1 eV and presented an excellent character with a low toxicity.
