Kiyoshi Shinoda scite author profile

The activity of Rh/CeO 2 for NO reduction by C 3 H 6 was gradually deceased by mixing with ZrO 2 until 68 mol%. Rh supported on CeO 2 -ZrO 2 with higher OSC was found to show lower catalytic activity. High OSC of CeO 2 -ZrO 2 would probably stabilize the surface of Rh in oxidized state, resulting in low activity and low efficiency of C 3 H 6 utilization for NO reduction. In situ FT-IR spectroscopy suggested that mononitrosyl species such as Rh(NO) d-and Rh(NO) d? are reaction intermediates in the NO-C 3 H 6 -O 2 reaction over Rh/CeO 2 -ZrO 2 catalysts.
