Using zeolite microcrystals as model micro building blocks, we have developed methods of organizing them into two- (2D) and three-dimensionally (3D) organized structures.1,2 The use of zeolite microcrystals as micro building blocks has additional merits since each zeolite microcrystal has millions of regularly spaced nanochannels and billions of nanopores which can be filled with a variety of functional molecules or nanoparticles. Therefore, we have intended not only to develop the ‘chemistry of micro building blocks’ but also to open a gateway to application of zeolites as advanced materials. This lecture summarizes various methods of organizing zeolite microcrystals into 2D functional entities such as monolayers, multilayers, and patterned monolayers on various substrates and 3D functional entities such as microballs and protein-zeolite composite fibrils. In the case of monolayer assembly, various types of linkages, types of substrates, the factors that govern the rate, degree of coverage, degree of close packing, degree of uniform orientation, and the average binding strength between each crystal and the substrate are described. The current and future applications of the organized products are also discussed.
Applications of zeolite films benefit from alignment of the integrated channels, but methods for film growth have nearly always introduced orientation randomization in the direction normal to the substrate. We have recently developed facile methods to grow silicalite-1 films and pure silica beta zeolite films on substrates with straight or sinusoidal channels positioned uniformly upright at thickness up to 8 microns.3 Precise gel compositions and processing temperatures are critical to promote secondary growth on pre-formed oriented crystal monolayers while suppressing self-crystallization in the bulk medium. The potential of these uniformly oriented films in nonlinear optical response and separation of xylene isomers is also presented.
