摘要：
The reduction behaviour under hydrogen of nickel catalysts supported on Al2O3, Nb2O5, TiO2 and ground glass carriers has been studied by thermoanalysis. The results show that the active component, NiO, interacts with Nb2O5 to form NiNb2O6 at 400-degrees-C, and at 900-degrees-C NiO interacts with Al2O3 and TiO2 to form NiAl2O4 and NiTiO3 respectively. The existence of the above-mentioned Support-Metal Strong Interaction (SMSI) was verified by in situ X-ray diffraction analysis. In the case of NiO/glass calcined at 900-degrees-C a new phase was formed; its composition has yet to be determined.
