英文摘要 | the silicon/aluminum ratio is proved to be a key parameter for mesoporosity tuning in the synthesis of hierarchical mfi zeolites by organosilane surfactant. at the fixed synthesis temperature, the mesopore size distribution evolves from a bimodal type to a uniform mode with the increase of si/al ratios. moreover, different si/al ratios result in opposite responses of mesopore distributions to the elevation of synthesis temperature. with the elevated temperature from 140 to 150 degrees c, the mesopore distribution of low-silica mfi zeolites (si/al-gel = 20) evolves from a bimodal type (centered at 4 and 10 nm) to a relatively uniform mode (centered at 8 nm), whereas the high-silica samples (si/al-gel = 40) exhibit a reverse transformation from a uniform mesopore distribution (centered at 3 nm) to a bimodal mode (centered at 4 and 20 nm). this work demonstrates alternative methods for the mesoporosity tuning of organosilane-directed hierarchical zeolites. |
