The basis of the ''N2O method'' of determining the surface area of copper catalyst is quantitatively tested. At temperatures of around 60-degrees-C only a surface monolayer of Cu(I) oxide is formed: this oxide is structurally different from a monolayer slice of Cu2O. EXAFS data show that the average particle diameter of Cu on SiO2 studied here is less than 25 angstrom. On the basis of our EXAFS and other studies, the surface oxide may be pictured in terms of oxygen atoms chemisorbed at the long… CONTINUE READING
