The presence and the evolution as a function of time of strongly adsorbed species during n-butane oxidation in a flow reactor was studied by "stopped-flow desorption" experiments and by thermogravimetric and Fourier-transform infrared analyses on a (VO)2P2O 7 catalyst highly active/selective in the conversion of n- butane to maleic anhydride....

Surface properties of a low-content vanadium catalyst, prepared by grafting a high-surface-area TiO 2 (anatase) support, have been studied by means of diffuse reflectance, e.s.r. and F.t.i.r. spectroscopy, t.p.d. and its catalytic activity by butadiene oxidation. It has been found that the grafting reaction of vanadium occurs on all surface OH...

The surface acidity of two (VO)2P2O7 catalysts with similar specific activities per square meter of surface area in 1-butene selective oxidation, but different specific activities in n-butane selective oxidation, was studied by ammonia, pyridine, acetonitrile, CO, and CO2 adsorption, by ammonia temperature-programmed desorption, and by...

The catalytic activity in the synthesis of methanol of cobalt-free and 2 atom % cobalt-containing Zn-Cr and Cu-Zn-Cr catalysts was investigated. The adsorption of hydrogen and CO was studied by FT-IR spectroscopy. It is suggested that small amounts of cobalt inhibit the catalytic activity of Zn-Cr catalysts through an inhibition of their...
