Development of photocatalytically active and environment friendly materials for water splitting applications rises to new challenges for scientists. In our work, novel composite materials based on TiO2/ZnO were studied for photonodic application for water splitting. The fabrication of the designed layers were simplified by usage of nanocolloids. In the present work, we will show how the properties of the composite materials can be changed through the parameters of fabrication. The morphological and microstructural properties were investigated by scanning electron microscopy (SEM), Energy-Dispersive X-ray (EDX) and X-ray photoelectron spectroscopy (XPS). DOS of the new materials were also estimated. From Impedance spectroscopy the modifications of band gap of synthesized layers were analyzed.
