Thermal stability of an SiO2-coated Rh catalyst and catalytic activity in NO reduction by CO.
An SiO2-coated Rh catalyst with SiO2 thickness of 13 nm has much higher stability against sintering of Rh and SiO2 than sol-gel and impregnation Rh/SiO2 catalysts; it exhibits the highest activity in the NO-CO reaction among these catalysts after thermal treatment.
