“…Solution combustion synthesis (SCS) is a very simple method allowing fast preparation of materials, which can be used as ceramic powders for a variety of technologies, including catalysts, gas sensors, and ceramic pigments. 24 SCS catalysts, in particular, have been applied in partial oxidation of methane, 25 DRM, 26 and aqueous hydrogenation of maleic acid. 27 Metal nitrate hydrates [M(NO 3 ) x •nH 2 O] are used as oxidizers, and urea (glycine, etc.)…”
