Hi,

i am pushpendra Kumar, working on ZnO, doped ZnO and Layered ZnO thin films for photo electrochemical splitting of water. as per my experience, ZnO has versatile applications. it simple to synthesize and its defect chemistry is very attractive. it is much better than TiO2 as its electron mobility is around 100 times more than TiO2. you can try to synthesize its nanoarchitectures by sol-gel hydrothermal method. It can be over layered by TiO2 to enhance its stability in high acidic or basic medium. ZnO is relatively less stable in Acidic or Basic medium under UV illumination therefore can be stabilized by coating tIo2 over it.

hi, but ZnO thin films still debate material in TCO,because of n type naturaly.We have to composite p-type ZnO(hole concentration above 10*20).If we will generate p-n junction, we will succesfull.but now not.
