摘要：

Air calcination of a Rh-Nb2O5/SiO2 catalyst (Nb : Rh =1 :1) at high temperature (900 degrees C) produced a single phase of RhNbO4 detected by X-ray diffraction. This catalyst system, followed by high-temperature reduction at 500 degrees C, was found to exhibit a strong metal-support interaction behavior from H-2 or CO chemisorption and ethane hydrogenolysis studies.
