Abstract Nanocrystalline Ti1-xCrxO2 (0 ≤ x ≤ 0.20) samples were synthesised via acid-modified sol-gel process and characterised with various techniques, such as HRTEM, FESEM, Raman, XPS, DTA and VSM. The TEM image of TiO2 exhibits elongated nanoparticles with an average size of 10 nm. The HRTEM in combination with selected area electron diffraction (SAED) reveals the interplanar spacing and polycrystalline nature of the samples, respectively.
