Abstract
A CO catalyst based on TiO2 with 12 wt% Pt platinum clusters has been synthesized. The catalyst was investigated by SRD and XRD methods. The catalyst was deposited on porous nickel. The effect of UV radiation on the catalytic properties was investigated and long-term tests were carried out for 180 days. It was found that UV radiation increases the reaction rate of CO oxidation by 3 times, decreases the activation energy of the reaction rate constant and increases the long-term stability of the catalytic properties. The activation energy of the reaction rate constant in the temperature range from 283 to 313 K was determined to be 23 ± 1 kJ/mol under UV illumination of the catalyst. The catalyst can be used in photocatalytic air purifiers.
