A set of standardized and realistic aftertreatment catalyst test protocols have been developed by the Advanced Combustion and Emission Control Technical Team in support of the U.S. DRIVE Partnership. The protocols are intended to accelerate the pace

Recent surface chemistry experiments help explain the operation of an exhaust gas NOx sensor that uses a platinum–gold alloy electrode to selectively remove oxygen but not NO from an interior chamber. The electrode surface must dissociate O2 for re

Prototype NOx sensors for use in automotive exhaust can contain Au/Pt electrodes that dissociate O2 for removal by electrochemical pumping, but these electrodes should not dissociate NO. In these sensors, the NO diffuses to a second chamber where it

A partial monolayer of Au strongly modifies the kinetics of water adsorption and formation on the stepped Pt(335) surface. The effects are more than passivation. With a Au coverage of 0.7 ML as measured by Auger spectroscopy, saturation H and O adsor

We have used temperature-programmed desorption with isotopically labeled gases to study O exchange between gas phase NO and adsorbed atomic O on Pt(335). We find two distinct types of adsorbed O, one of which exchanges at least 40 times faster than t

The authors have studied the adsorption and reaction of oxygen and CO on a stepped Pt surface with varying amounts of Au, using temperature-programmed desorption and reaction (TPD and TPR), low-energy electron diffraction (LEED), high-resolution elec

As part of a study of species important in automotive exhaust chemistry, the reactivity of atomic N and NO on Pt(335) at low temperature has been studied. The atomic N was produced by dissociating adsorbed NO with a 76 eV electron beam. Cross section
