TLDR
The chromatographic technique for determining the specific copper surface area of catalysts by reaction with nitrous oxide has been investigated in this paper, where the application of a single pulse of Nitrous oxide in excess of that required to oxidize an the surface copper and a temperature of 90°C has been shown to provide a reliable measurement of specific copper surfaces.About:

The activity and state of the copper surface in methanol synthesis catalysts
TL;DR: A frontal chromatographic version of this technique has been developed which is very suitable for in situ measurements and this has enabled the apparent copper areas of various catalysts to be measured after exposures to methanol synthesis gases of different compositions at typical industrial conditions in microreactors commonly used for assessing the methenol synthesis activity of such catalysts as discussed by the authors.

Noble metal catalysts for the preferential oxidation of carbon monoxide in the presence of hydrogen (PROX)
TL;DR: In this article, the influence of the noble metal nature (Pt, Ir, Pd), the support physical and chemical properties (redox, acidity, basicity) and the reaction conditions (oxygen stoichiometry) on the catalyst activity and selectivity was evaluated.

A direct determination of the anisotropy of the surface free energy of solid gold, silver, copper, nickel, and alpha and gamma iron
TL;DR: In this article, the surface free energy of all the f.c.c., b.c, and alpha-iron surfaces was analyzed and the effect of oxygen on the γ plots of a number of F.c.c. metals was established as deepening the {100} and {111} cusps.

Reaction of nitrous oxide with copper surfaces. Application to the determination of free-copper surface areas
TL;DR: In this paper, a study on the reaction of nitrous oxide with copper surfaces was made, where the reaction at 90°C and 20 cmHg gave a coverage of about unity, and was used for determining free-copper surface areas of catalysts.
