Publikováno v: Catalysis Communications, Vol 148, Iss , Pp 106163- (2021)

The catalytic decomposition of ozone was carried out at 40 °C with a Pd/Al2O3 catalyst, in the presence or absence of nitrogen oxides traces. NOx were produced during the generation of ozone from air. Two set-ups were used to examine the possible ef
