The aim of the study was to examine how the palladium precursors such as Pd(NO3)2 or PdCl2 and the reducers added (hydrazine hydrate or EDTA) influence methane combustion activity of monolithic palladium catalysts. Palladium nitrate was found to be a better Pd precursor, and the catalysts obtained displayed a noticeably higher activity in methane oxidation. The addition of hydrazine hydrate to 1% Pd/Al2O3 catalyst increased its activity when PdCl2 was used as the palladium precursor. With Pd(NO3)2 as the palladium precursor, the addition of reducers - hydrazine hydrate or EDTA - decreased the activity of the monolithic palladium catalysts tested.
