Abstract

The reduction of N2O by C1 to C4 alkanes Over Pd/SiO2 under stoichiometric conditions has been investigated. The reaction using propane is much faster than the corresponding reaction over silica-supported Pt or Rh. Isobutane reacts with N2O at a similar rate to propane while ethane is somewhat less reactive and methane unreactive except transiently after oxidising pretreatments. The difference in activity between alkanes correlates with the C-H bond strength. The N2O/propane reaction is quenched by low concentrations of O2 but activity recovers immediately it is removed. Water also inhibits indicating that part of the palladium is oxidised under reaction conditions.
