On the surface coverage of alumina by molybdenum-oxide in nickel - And cobalt-promoted MoOx/Al2O3 catalysts
The chemisorption Of CO2 has been studied on alumina-supported Co-and Ni-promoted molybdenum-oxide (CoMo, NiMo) and, besides those, on monometallic Co and Ni. Chemisorbed amounts on the monometallic samples were equal to that on the alumina support. XPS measurements were performed with the NiMo and Ni samples. The amounts of surface Mo- and Al-ions were calculated. It could be established that molybdenum oxide forms a near to monomolecular layer on the Co- and Ni-promoted molybdena-alumina samples.
