Methane Catalytic Combustion under Lean Conditions over Pristine and Ir-Loaded La_1-xSr_xMnO₃ Perovskites: Efficiency, Hysteresis, and Time-on-Stream and Thermal Aging Stabilities.

ABSTRACT: The increasing use of natural gas as an efficient, reliable, affordable, and cleaner energy source, compared with other fossil fuels, has brought the catalytic CH₄ complete oxidation reaction into the spotlight as a simple and economic way to control the amount of unconverted methane escaping into the atmosphere. CH₄ emissions are a major contributor to the 'greenhouse effect', and therefore, they need to be effectively reduced. Catalytic CH₄ oxidation is a promising method that can be used for this purpose. Detailed studies of the activity, oxidative thermal aging, and the time-on-stream (TOS) stability of pristine La_1-xSr_xMnO₃ perovskites (LS_XM; X = % substitution of La with Sr = 0, 30, 50 and 70%) and iridium-l
