摘要 采用水热合成法制备了不锈钢负载的ZSM-5分子筛涂层.考察了不锈钢载体表面处理对分子筛与载体之间结合力的影响.研究结果表明,与酸处理或洗涤剂清洗处理相比,高温热处理更加有利于提高分子筛与不锈钢载体之间的结合力,且热处理效果与温度有关,最佳处理温度为850℃,在该温度下处理5 h后的载体,所得到的分子筛/不锈钢复合材料,不仅具有最大的分子筛表面覆盖率,而且在焙烧过程中分子筛几乎不脱落.热处理后的载体在反应液中进一步浸泡同样会影响分子筛的覆盖率及结合力,影响大小与载体热处理温度有关. ZSM-5 coatings supported on stainless steel foils were synthesized by hydrothermal synthesis. The influence of support surface pretreatment was studied on the adhesion strength between zeolite crystals and stainless steel support. The results showed that the high-temperature pretreatment had more favorable effect on the adhesion strength of zeolite coatings as compared with acid the treatment or by cleaning with detergent, the degree of which depends on the temperature. ZSM-5 coatings with the highest coverage and the strongest adhesion strength achieved on stainless steel support was obtained by pretreating at 850 ℃ for 5 h. The immersion of high-temperature pretreated support in the reaction solution also imposes influence on surface coverage and adhesion strength of zeolite coatings, the degree of which depended on the pretreatment temperature too.
