Abstract

Zinc oxide (ZnO) thin films of different thickness have been deposited onto glass/FTO substrates by spray pyrolysis method. The films were characterized by XRD, optical transmittance, Reflectance and SEM techniques.All the films are polycrystalline with hexagonal wurtzite structure, with c- axis growth (002) perpendicular to substrate surface. Starch was hydrolyzed by novel Photoelectrocatalytic process. Hydrolyzed starch was found to contain 60µg ml-1 of glucose and 100µg ml-1 ofmaltose.
