Multilayer TiO(2) Inverse Opal with Gold Nanoparticles for Enhanced Photocatalytic Activity

[Image: see text] Three-dimensional highly ordered multilayer titanium dioxide (TiO(2)) inverse opal (TIO) structures with two pore sizes were fabricated over a large surface using a self-convective method. The fabricated TIO multilayers were functionalized with gold nanoparticles (AuNPs) by immersi...

description [Image: see text] Three-dimensional highly ordered multilayer titanium dioxide (TiO(2)) inverse opal (TIO) structures with two pore sizes were fabricated over a large surface using a self-convective method. The fabricated TIO multilayers were functionalized with gold nanoparticles (AuNPs) by immersing the samples in solution with gold nanoparticles. The photocatalytic activity of TiO(2) was enhanced by 85% via plasmonic activation of AuNPs that increased the lifetime of photogenerated holes and electrons. The improved photocatalytic activity was characterized with both UVA and visible light irradiation using an in-house built gas-phase photoreactor.
