"Direct imaging of catalytically important processes in the oxidation of CO over RuO₂(110)";
Journal of the American Chemical Society, 123 (2001), S. 11807 - 11808.

Ruthenium dioxide (Ru#O_{2}) reveals unique and promising redox properties, making RuO2 a potential candidate for a versatile oxidation catalyst.
Recently Zhang and Kisch reported, for instance, that RuO₂ is a robust and efficient catalyst for room temperature (RT) oxidation of CO by humid
air; recall that typical metal oxides do not tolerate humidity. In this contribution we present scanning tunneling microscopy (STM) data which
directly image the catalytically important processes occurring on the RuO₂(110) surface after exposing the pristine surface to CO and O₂. These
data are complemented by density functional theory (DFT) calculations.
