We conduct a mechanistic study of one Daihatsu Intelligent Catalyst system, Pt-CaTiO3, for three-way automotive catalysis, using atomic-resolution electron microscopy and related spectroscopic techniques. Our results on model thin film and powder catalysts show the Intelligent Catalyst reaction, though to a lesser extent than has been reported.
