Abstract

The impact of UV and VIS irradiation and specific nitrogen modification on a 5%Cu/5%TiO2/SiO2 catalyst in the course of oxidation of ammonia was investigated. It was demonstrated that both UV and VIS irradiation increased the conversion of the reactant in the reaction studied. Due to a good distribution of titanium dioxide and copper on the surface of the support, higher ammonia conversion was achieved. Physico-chemical characterisation of the catalysts studied using methods such as BET, SEM-EDS, TPD (NH3), and TPD (CO2) was carried out.
