| Abstract: | Up to date, there is no satisfactory method to measure the strength and number of basic centers of metal oxides. Based on the theory of selective intermolecular force, a new method of applying nitromethane as molecule probe (it's-NO2 group being very weak, nearly inert) with gas chromatographic and TPD technique has been proposed in this paper, because
the C=O group of acetic acid in the previous adsorption method may interact with metal ion and then may interfere the measurement of basic centers. |
