Catalytic oxidation of NO to NO2 for nitric acid production over a Pt/Al2O3 catalyst
Salman, Ata ul Rauf; Enger, Bjørn Christian; Auvray, Xavier; Lødeng, Rune; Menon, Mohan; Waller, David; Rønning, Magnus (Peer reviewed; Journal article, 2018)The oxidation of nitric oxide (NO) to nitrogen dioxide (NO2) is a key step both in NOx abatement technologies as well as in the Ostwald process for nitric acid production. A 1 wt.% Pt/Al2O3 catalyst was used to study ... -
Challenges in quantifying Pt concentrations in Pd alloys by using secondary ion mass spectrometry: Strong grain orientation effects
Holme, Børge; Håkonsen, Silje Fosse; Waller, David (Peer reviewed; Journal article, 2024)Palladium–platinum alloys were analysed by dynamic secondary ion mass spectrometry (SIMS) to investigate grain orientation effects that gave differences of up to 400% in the Pt/Pd count rate ratios, even within the same ... -
Redox transformations of Ru catalyst during NO oxidation at industrial nitric acid production conditions
Gopakumar, Jithin; Martin Benum, Pål; Svenum, Ingeborg-Helene; Enger, Bjørn Christian; Waller, David; Rønning, Magnus (Peer reviewed; Journal article, 2023)Oxidation of nitric oxide is one of the main steps in the Ostwald process for industrial nitric acid production. This work summarises the use of - supported Ru catalyst to study the oxidation of NO to NO at ambient and 4 ...
