摘要

A new strategy was introduced to decompose KNO₃ and generate strong basic sites at the temperature as low as 723 K and the base strength (H_-) of 15.0-18.4 was measured on KNO₃/NaY composites. The basic sites produced were further characterized by FTIR, CO₂-TPD and titration of basicity. The redox interaction between loaded KNO₃ and methanol was proved to be accounted for the generation of basic sites on KNO₃/NaY composites and the interaction pathway was proposed by evacuated FTIR and TG/MS. In comparison with the conventional thermal approach, the redox process could also suppress the release of NO_x from KNO₃ decomposition according to the results of the colorimetric method and TG/MS. In addition, solid bases KNO₃/NaY were firstly employed to catalyze the vapor phase methylation of cyclopentadiene (CPD). The basic sites generated through the interaction between KNO₃ and methanol were catalytically active for CPD methylation.
