In this work, Sn1-xMoxO2 (x = 0.00, 0.01, 0.02, 0.04) nanoparticles powders were produced successfully at room temperature using the co-precipitation method. These types of nanoparticles are widely used as a dopant for photo anodes due to its thermal stability and unique electronic configuration, it exhibits different oxidation states. The structural and optical characterization of the nano-powders were investigated by DRX, FTIR, and UV-Visible spectroscopy techniques. The DRX measurements showed that all samples had a tetragonal rutile structure of polycrystalline SnO2 and the (110) preferential orientation of the undoped sample remains with 1%, 2% and 4% Mo doped SnO2 samples. Also, the grain size and the micro-deformation are calculated by Williamson-Hall and Debye-Scherrer formulas, the grain size is approximately between 8nm and 10nm. The presence of a band at 632 cm-1 in the FTIR spectrum confirms the existence of the O-Sn-O bond.
