摘要：

On niobium oxide catalysts, induction period was observed during 1-butene isomerization, because surface strong adsorption sites for 1-butene existed. With sodium-loading on Nb2O5/Al2O3, new and weak basic sites such as Nb-O-Na-OH were formed. Nb2O5 supported on TiO2 functioned as a sensor for oxygen and nitrogen monoxide.
