沸石是一种纳米多孔铝硅酸盐晶体，具有多种有趣的性质和工业应用。沸石有超过140种合成的分子筛框架拓扑，每种分子筛都有自己的组成范围，沸石可以在非常高的温度下提供尺寸、形状和静电选择性吸附、扩散和反应。沸石被广泛用作石油催化剂、干燥剂、离子交换剂和过滤器、环保洗涤剂以及分离化学混合物的分子筛。可以肯定地说，沸石提供了丰富的纳米技术。沸石所提供的结构和化学上的通用性强烈表明，这些材料还有其他的应用前景。在过去的几年里，人们对微波加热沸石在化学过程中的应用产生了浓厚的兴趣，如催化剂合成、离子模拟微波加热在沸石纳米孔中的扩散
Zeolites are nanoporous crystalline alumino-silicates with a rich variety of interesting properties and industrial applications. With over 140 zeolite framework topologies synthetically available—each with its own range of compositions—zeolites offer size-, shapeand electrostaticallyselective adsorption, diffusion and reaction up to remarkably high temperatures. Zeolites are widely used as petroleum catalysts, desiccants, ion exchangers and filters, environmentally safe detergents, and as molecular sieves for separating chemical mixtures. It is safe to say that zeolites offer a rich array of nanotechnologies. The structural and chemical versatility offered by zeolites strongly suggests that other applications lie ahead for these materials. During the past few years, a flurry of interest has emerged in using microwave-heated zeolites in chemical processes, such as catalyst synthesis, ion Simulating Microwave-Heated Diffusion in Zeolite Nanopores
