N2O decomposition properties of Ru catalysts supported on various oxide materials and SnO2

Abstract Nitrous oxide (N2O) is a stratospheric ozone depleting greenhouse gas that has global warming potential. As the catalytic decomposition of N2O is one of the most promising techniques for N2O emissions abatement, in this study, for this purpose the properties of Ru supported on various oxide...
