Abstract: This paper describes how the surface structure of the catalysts of the systems NiO-SiO2 and NiO-Cr2O3-SiO2 is studied and determined by using the molecule probe method.The conclusions obtained with the method have been verified to be correct by means of TPD, X-ray diffraction and magnetic analyses etc. And as a result the method is proved to be a new effective one for studing the surface structure.This method is characterized by rapidly gathering information about surface structure of adsorption centre of catalysts in a convenient way under Closely practical conditions of reaction.
