Effects of support materials and Ir loading on catalytic N2O decomposition properties

Effects of support materials and Ir loading on catalytic N2O decomposition properties

N2O is a stratospheric ozone-depleting greenhouse gas with a global warming potential. The catalytic decomposition of N2O is one of the most promising and economical techniques to reduce the amount of the gas in the atmosphere. In the present study, the effects of support materials and Ir loading on...
