Fabrication of Porous Nanoflake ZnO

摘要

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. Sample crystallinity and morphology before and after calcinations were characterized by XRD, FTIR and SEM. Porosity profile was evaluated to its particle structure using N_2 adsorption-desorption. Surface area was calculated using BET and it was 15 m~2/gram.
