Single-atom metal catalysts offer maximized material efficiency, but there is large room to improve the intrinsic activity per metal atom for many reactions. Here, the authors demonstrate that the solution for CO oxidation is to tackle the issue of l

The activity and hydrothermal stability of the Rh/CexZr1-xO2 (x = 0, 0.05, 0.3, 0.5) model three-way catalysts for gasoline vehicle emissions control were investigated in this work. Among the Rh/CexZr1-xO2 samples with different Ce/Zr ratios, the Rh/

Despite the maximized metal dispersion offered by single-atom catalysts, further improvement of intrinsic activity can be hindered by the lack of neighboring metal atoms in these systems. Here we report the use of isolated Pt1 atoms on ceria as “se

Effective control of hydrocarbon (HC) emissions at low temperatures is critical for emission compliance, since a large fraction (typically 70–80%) of tailpipe HC emissions occurs during the first couple of minutes after an engine cold-start. The ox

Since converter performance is a complex function of operating conditions, converter geometries, and catalyst properties, an empirical approach to the problem can be very costly and time consuming; thus mathematical modeling promises to be helpful in

Pt is an active component in diesel oxidation catalysts (DOCs) but it ripens to form large particles at elevated temperatures due to significant vapor phase transport of PtO2. Adding Pd improves the durability of the catalyst but there is no clear co
