“…Previous work (section 2.3) indicates that LaNiO3 can capture Pt and Rh through B-site substitution in the system LaNi1-xM'xO3, M' = Pt, Rh. The current work is a study to establish a knowledge-base on the synthesis and structural aspects of Pt-and Rh-containing perovskites, while Pt-catchment using oxides is addressed in a different PhD work [148]. The focus of the section is the stoichiometric double perovskites RE2MM'O6 (RE = La, Nd, Y; M = Ni, Co, Fe; M' = Pt, Rh) with particular attention to B-site ordering and oxidation states.…”

“…It can reduce costs, reduce the use of scarce noble metals and provide a system with a similar or lower pressure drop than the gauze-based system (the oxide pellets from the N2O decomposition catalyst provide a low pressure drop; section 2.1). A PhD project is currently ongoing in the iCSI centre for the study of Pt-catchment using oxide materials [148].…”
