A research  to synthesis and characterizes nanosized TiO2 particles on activated carbon (AC) were prepared by deep coating. Nanotechnologies are a set of methods and techniques for the treatment of matter and aimed at obtaining materials with novel functionalities and improved characteristics. In this research, the preparation TiO2/AC composites was carried out in several stages, the first stage was prepared active carbon from empty palm oil bunches, then synthesized TiO2 nanoparticles and last step was synthesis nanosized TiO2 particles on activated carbon (AC) using deep coating method. The TiO2/AC composites were characterized  by various methods such as Fourier Transmission Infrared spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscope (SEM). The XRD pattern of synthesized of the TiO2 nanoparticles shown one strogest peak, that indicative the prepared sample is single crystal  structure.  The crystallite size of the Titanium dioxide nanoparticles is 79,6 nanometer. SEM photo analysis of the morphology of TiO2 particles with uneven white clumps on the surface of activated carbon in the form of porous bars of non-uniform size. Based on this study  has reported the properties of TiO2/AC has been considered  used in photocatalysis  of the degradation of substances in an aqueous solution and the reduction of inorganic ions
