The Superiority of TiO₂ Supported on Nickel Foam over Ni-Doped TiO₂ in the Photothermal Decomposition of Acetaldehyde.

ABSTRACT: Acetaldehyde decomposition was performed under heating at a temperature range of 25-125 °C and UV irradiation on TiO₂ doped by metallic Ni powder and TiO₂ supported on nickel foam. The process was carried out in a high-temperature reaction chamber, "The Praying Mantis^TM", with simultaneous in situ FTIR measurements and UV irradiation. Ni powder was added to TiO₂ in the quantity of 0.5 to 5.0 wt%. The photothermal measurements of acetaldehyde decomposition indicated that the highest yield of acetaldehyde conversion on TiO₂ and UV irradiation was obtained at 75 °C. The doping of nickel to TiO₂ did not increase its photocatalytic activity. Contrary to that, the application of nickel foam as a support for TiO₂ appeare
