Mechanistic insight into the improved photocatalytic degradation of dyes for an ultrathin coating of SiO₂ on TiO₂ (P25) nanoparticles

The photocatalytic mechanism of TiO₂ (P25) nanoparticles coated with SiO₂ (SiO₂:TiO₂) by atomic layer deposition was investigated. The deposition of SiO₂ on TiO₂ not only gives a photocatalytic improvement for the degradation of both Rhodamine B (3.6–fold) and Acid Blue 9 (3...

Synthesis of a rationally designed multi-component photocatalyst pt:Sio₂:Tio₂ (p25) with improved activity for dye degradation by atomic layer deposition

Photocatalysts for water purification typically lack efficiency for practical applications. Here we present a multi-component (Pt:SiO₂:TiO₂ (P25)) material that was designed using knowledge of reaction mechanisms of mono-modified catalysts (SiO₂:TiO₂, and Pt:TiO₂ ) combined with the...
