Abstract


Lamellar porous ZnO has been synthesized at room temperature with the help of anionic surfactant SDS and characterized by XRD, SEM, TEM, PL, UV-Visible and FTIR spectroscopy. In the present investigation, SDS a peculiar surfactant act like a template and catalyses to the self-assembled growth of lamellar structure. Obtained structure is anisotropic lamellar in form with multiple secondary nucleation flaps growing perpendicular to a central lamina with uniform morphology. Photocatalytic activity of as synthesized ZnO on the degradation of bromophenol blue is also studied. The percentage of decolourization of dye was found 84.2% to 77.4% in first 30 min at 431 nm and 590 nm.
