Preparation of Co_2TiO_4/CoTiO_3/Polyaniline ternary nano-hybrids for enhanced destruction of agriculture poison and organic dyes under visible-light irradiation

摘要

Co2TiO4/CoTiO3/Polyaniline ternary nano-hybrids were fabricated via sol-gel method and new gelling agent. The varied preparation factors like the type of calcination temperature, solvent and gelling agent were studied through the dimension and morphologies of final products. The photocatalytic activity of the Co2TiO4/CoTiO3/Polyaniline was verified via destruction of changing pollution like as diazinon, methylene blue, eosin Y, methyl orange, and phenol red. The maximum percentage of destruction of organic pollutions was found to be for diazinon (98.3%). The BET analysis demonstrated that the preparation of nano-hybrids in both of presence valine and of phenylalanine can increase surface from 1.05 m(2)/g to 13.50 m(2)/g. The obtained ternary nano-hybrids were characterized through EDX, TEM, XRD, DRS, VSM, SEM, and FT-IR.
