The specific copper surface areas in Cu/ZnO methanol synthesis catalysts by oxygen and carbon monoxide chemisorption: evidence for irreversible CO chemisorption induced by the interaction of the catalyst components

摘要: Abstract The chemisorption of oxygen and carbon monoxide has been employed to determine the copper metal surface areas Cu ZnO methanol synthesis catalysts in compositional range = 0 100 . total, reversible irreversible adsorption capacities for have measured at 78 293 K, respectively. CO show good linearity with O 2 lie on a line connecting capacity pure that, zero intercept, zinc oxide. Thus, crystalline these biphase evaluated from specific having stoichiometry Cu:O 2:1. Chemisorption also is measure area but associated defect sites, attributed nonmetallic species A critical comparison another traditionally method, N decompositive Chemisorption, shows that low temperature preferred, reliable technique determination areas.
