Abstract
We report the synthesis of a TiO2/Ag binary nanocomposite with high activity for visible-light-driven photocatalysts using graft copolymerization: (1) conversion of terminal OH groups on the surface of TiO2 nanoparticles to Cl groups, (2) graft polymerization from TiO2–Cl via ATRP with ionically charged poly(styrene sulfonic acid), (3) ion exchange process with an AgNO3 solution following sintering. TiO2/Ag binary nanocomposite showed enhanced photocatalytic performance for the degradation of methyl orange under visible light illumination. The improved photocatalytic performance of the TiO2/Ag binary nanocomposite was due to the plasmonic effect, recombination rate of electron–hole pairs that was suppressed by Ag nanoparticles.
