Resumo

A CO catalyst based on TiO2 was synthesized with additions of 10 wt % TiC0.2N0.8 and 10 wt % Pd. The catalyst was tested by TEM, X-ray photoelectron spectroscopyand X-ray patterns. The effect of UV radiation on catalytic properties was investigated and long-term tests were carried out for 100 days. UV radiation was found to increase the rate of the CO oxidation reaction, decrease the activation energy of the reaction rate constant, and increase the long-term stability of the catalytic properties. The activation energy of the reaction rate constant is determined in the temperature range from 288 to 308 K, which is equal to 23 ± 1 kJ/mol under UV illumination of the catalyst. The catalyst has good prospects for use in photocatalytic air cleaners.
