- 中文摘要: The chemisorptive properties of the nickel borides have been studied with temperature programmed desorption of H/sub 2/ and CO. The TPD chromatograms of H/sub 2/ show two major peaks at 150.degree.C and 300.degree.C for the P-1 and P-2W nickel borides and a major peak at 150.degree.C for the DBNi and CrP-1 nickel borides. Not all hydrogen molecules are dissociatively adsorbed on surface nickel, some hydrogens diffuse and are absorbed into the matrix of the nickel borides. Except the Cr- promoted P-1(P-2W), the nickel borides do not exhibit the obvious chemisorptive capacity for CO. The Cr-promoted nickel borides, on the other hand, not only have the obvious uptake capacity for CO but also have the good activity for CO dissociation.
