Abstract

Problem statement: Nano-scale porous ZnO with high surface area have been studied to enhance physicochemical and electrochemical properties of certain optoelectronic devices applications. Approach: ZnO porous structure consists of flake-shape particles was synthesized through pyrolitic reaction of hydrozincite as Chemical Bath Deposition (CBD) product. Flake-like particle perpendicularly lied on substrate was obtained after 24 hours deposition. After calcinations, cavities on particle surface were observed as additional pores. Result: Sample crystallinity and morphology before and after calcinations were characterized by XRD, FTIR and SEM. Porosity profile was evaluated to its particle structure using N2 adsorption-desorption. Surface area was calculated using BET and it was 15 m2 gram-1. Conclusion: The particle growth in CBD technique had been observed through its morphology and crystalline structure. Macropores structure was formed by cavities among the nanoflakes lied random on substrate and give surface area of 15.1866 m2 gram-1.
