Preparation and Characterization of (CO<sub>3</sub>O<sub>5</sub>, Fe<sub>2</sub>O3: Sn) Nanocomposite for Sensitize Photoelectrodes

Preparation of nanocomposite ( CO 3 O 5 ,Fe 2 O3: Sn ) was chemically held from its raw materials as a first step of this research in order to manufacture photoelectrode , this nanocomposite was deposited on substrate glass using spraying technique and heat treatment by Nd: YAG laser pulse (LPD) . Experiments were conducted to study the surface topography of the nanocompound by (AFM) to determine the roughness of the prepared electrode, In addition, the structure characteristics were studied using the x-ray diffraction (XRD) to determine the main phase. The second step of this research was designing a glass electrolysis cell containing our nanoelectrode and producing hydrogen. Finally the electrochemical parameters of the designed cell were studied Key words: nanocomposite (CO 3 O 5 ,Fe 2 O 3 :Sn), Nd: YAG laser pulse (LPD) , Photoelectrodes; atomic force microscope.
