ZnO nanostructured photocatalysts for water treatment applications

Metal oxide semiconductor meterails, designed to be applied in photocatalytic systems for water purification, are required to have large specific surface areas, because chemical reactions induced by suitable irradiation take place by contact between their surface and fluid. Zinc oxide is well known as a material that forms various morphologies at the micro- and nanoscale, which can fulfill this requirement. Like most of the photocatalytic semiconductors, it has a band gap in the ultraviolet region. Photocatalytic gradation of an organic dye, as a model pollutant, was studied in aqueous solutions using nanostructures of zinc oxide synthesized in the form of prism, spiky stick and grass blade. They were grown from a solution and their entire morphology was simply controlled by varying the growth conditions, without using any capping or surfactant agents. Detailed characterization of their structure and porosity on the micro- and nanoscale was performed by scanning electron microscope and X-ray scattering measurements. All nanostructures exhibited notable photocatalytic activities. However, remarkable results were achieved with nanostructures in the form of grass blade, which exhibited enhanced photocatalytic activity, even in sunlight. This was ascribed to their specific morphology characterized with a high degree of mesoporosity.
