摘要：
The improving effect of Sr in the catalytic activity of Rh for N2O decomposition has been studied under 1,000 ppm N2O/He and 1,000 ppm N2O/5% O2/He (GHSV = 10,000 h−1). Different techniques have been used for catalysts characterization: TEM, SEM-EDX, XRD, N2 adsorption at −196 °C and in situ XPS. Sr favours the Rh dispersion and reduction under reaction conditions, and allows the low temperature removal of N2O in the presence of O2 (100% decomposition at 350 °C).
