“…While under ideal conditions (atomic flatness), sufficient linkages are possible between adjacent surfaces, in real systems with significant surface roughness, the chances of forming effective interconnecting linkages become much smaller if interactions occur on the short range. [164] Another issue is the time scale. While molecular diffusion across a surface may only take seconds for 10 nm nanoparticles, it can take months for micron-sized colloids.…”

Colloidal Assembly: The Road from Particles to Colloidal Molecules and Crystals

Colloidal particles may be considered as building blocks for materials, just like atoms are the bricks of molecules, macromolecules, and crystals. Periodic arrays of colloids (colloidal crystals) have attracted much interest over the last two decades, largely because of their unique photonic properties. The archetype opal structures are based on close-packed arrays of spheres of submicrometer diameter. Interest in structuring materials at this length scale, but with more complex features and ideally by self-assembly processes, has led to much progress in controlling features of both building blocks and assemblies. The necessary ingredients include colloids, colloidal clusters, and colloidal "molecules" which have special shapes and the ability to bind directionally, the control over short-range and long-range interactions, and the capability to place and orientate these bricks. This Review highlights recent experimental and theoretical progress in the assembly of colloids larger than 50 nm.

“…Among various covalent linkages (Figure 4a-g) 3,4,6,8,15,19 the ether linkage formed by reaction between surfacetethered halopropyl groups and hydroxyl groups ( Figure 4g) 4 has been most widely used due to its simplicity. Characterization of different types of linkages in terms of number density, thickness, and roughness of each linker was possible by X-ray reflectivity.…”

This Account summarizes various methods of organizing zeolite microcrystals into two-dimensional functional entities such as monolayers, multilayers, and patterned monolayers on various substrates and three-dimensional functional entities such as microballs and protein-zeolite composite fibrils. In the case of monolayer assembly, various types of linkages and substrates, factors that govern the rate, degree of coverage, degree of close packing, degree of uniform orientation, and average binding strength between each crystal and the substrate are described. The current and future applications of the organized products are also discussed.

“…Among them, fabrication of nanoporous materials using a chemical glue can be used for implementing nanoscopic or microscopic arrays of these materials. So far, there have been a few reports on the utilization of chemical glues such as inorganic glue [93], nano-glue [94], and organic covalent linkers [95]. Recently, we reported microwave fabrication of zeolites directly from the synthetic solution and proposed the incorporation of a transition metal as nano-glue [96].…”

IntroductionZeolites are crystalline inorganic materials with unique, characteristic micropores. These micropores in molecular scale, which have one to three dimensions, are due to interconnected cavities or channels. The types of assembly of cavities or channels control the size of micropores, orientation of microporous channels, and the morphology of zeolite particles. Undoubtedly, the morphology is originally related to the framework type and also closely related to the micropore size, crystal size, and shape, and directly affects the physicochemical properties of zeolites.Zeolites are extensively used in the fields of heterogeneous catalysis, separations, ion exchange, chemical separation, adsorption, host/guest chemistry, microelectronic devices, optics, and membranes [1][2][3][4]. Such applications of zeolites are strongly affected by the pore size, type of channels, and morphologies [5-9]. Morphological synthesis of zeolites is particularly important in catalytic applications where the particle shape can have a dramatic effect on the product distribution due to differences in rates of transport/diffusion and reaction. Recent research interests have also been directed toward the crystallography of single zeolite crystals by applying nanotechnology. Thus, there has been a great interest in developing synthetic approaches to control crystal size and morphology of zeolites [9][10][11].Fine-tuning of zeolite crystal size and shape is usually accomplished by systematic variation of the composition of the precursor mixture (including the use of additives such as salts) [12]. But through the development of new technology and equipment, synthetic parameters such as temperature, pressure, and stirring rate or even gravity can be controlled.This chapter provides a brief introduction to the morphological synthesis of zeolites and related fabrication methods such as as microwave. Examples in the preparation of well-shaped single crystals, fine control of common particles, and microwave driven fabrication are discussed.
