摘要：

The catalytic activity of a ZrO2/SO4 catalyst in the isomerization of n-butane at 423 K is reversibly suppressed by addition of CO. IR analysis of the adsorption of CO indicates that the only sigma-coordination of CO onto coordinatively unsaturated surface Zr4+ cations occurs in the 300-473 K interval.
