Fabrication of hollow zeolite spheres using oil/water emulsions as templates

Preparation of porous thin-film polymethylsiloxane microparticles in a W/O emulsion system

“…Similar studies have also been reported for other metal oxides such as zeolite [29][30][31][32][33] and titania. [34][35][36] Among metal oxides of special morphology, porous thin-film microparticles of 1-10 μm in diameter and 1-100 nm in thickness are also interesting as a functional material.…”

A facile method for the fabrication of IM-5 hollow zeolite sphere in emulsion system

“…According to the previous reports, the synthesis system mainly adopted hard sphere-like templates, such as polystyrene spheres [11][12][13][14], mesoporous silica spheres [15,16] and carbon black [17] to prepare HZSs. Recently, there are few reports utilized oil in water (O/W) surfactant emulsion soft template to synthesis silicate-1 HZSs [18]. Among these methods, two main steps are as follows: (1) the core-shell electrostatic interaction process (for example, layer-by-layer self-assembly), (2) the core sacrificial strategy.…”

Synthesis and Catalytic Application of Zeolite-Based Hollow Materials

“…28 Yue and coworkers first synthesized hollow zeolite spheres of silicalite-1 using oil/water emulsions as templates. 50 The oil-in-water (O/W) emulsions contain toluene, water and silicalite-1 nanocrystals, in which the toluene was as the template and ensured the zeolitic shells remained intact after hydrothermal treatment, and silicalite-1 nanocrystals act as both the emulsifier and stabilizer. The fabrication procedure is depicted in Figure 5.…”
