【摘要】 纳米分子筛表现出许多独特的物理性质,如高外比表面积和丰富的表面硅羟基,具有独特的催化性能和对气体的分离能力。总结了近年来在纳米分子筛的合成、表征、性质及应用方面的最新研究进展。认为将纳米分子筛通过原位晶化技术组装到一定基质上,使其具有梯度分布的孔结构、合适的酸性和高的水热稳定性,将会成为今后发展的趋势。更多还原

【Abstract】 Nano-zeolites with unique physical-chemical properties such as high dispersibility and abundant surface hydroxyls are playing important role in catalysis and gas separation and thus much attention has been given to the synthesis of various nano-zeolites in recent years. The advances achieved in the synthesis, characterization and application of nano-zeolite are reviewed. It is suggested that assembly of nano-zeolite on the matrix could be a potential way to making composite with proper structure, high acidity and excellent hydrothermal stability.更多还原
