在分子筛制备过程中,怎么理解“an annealing step”??将这部分原文附上。The solution was removed after 60 h and immediately cooled to room temperature. The crystalline product was isolated from the supernatant by three centrifugation and washing cycles of the mother liquor with DI water at 13 000 rpm for 40 min. The water was decanted, leaving behind a gel containing the ZSM-5 crystals. For protocols without an annealing step, a portion of the ZSM-5 gel was removed and dried in air for further characterization, while the remaining gel was directly added to a silicalite-1 growth solution (without drying) to prepare coreshell particles.一直没有理解~文章中说,通过引入退火处理,使得合成了表面光滑的球状ZSM-5 分子筛 。很不理解这个退火处理?有没有人懂的,能不能讲一下?查看更多12个回答 . 18人已关注
