A novel belt-like silicalite-1 nanocrystal with narrow mesoporosity had been synthesized by hydrothermal method. In the synthesis process, nanosized Ca(OH) 2 was used as a hard template due to the fact that it was rich in pores and could be insoluble in water. A subsequent acid washing with dilute HCl removed the nanosized Ca(OH) 2 further uncovering mesopores. A study was carried...
A new method was developed for preparation of silicalite-1 microspheres with uniform diameter about 2.5μm using monodispersed micron-sized poly- styrene-co-divinylbenzene (PSD) porous particles as template. In this method, the PSD particles were impregnated first with tetraethoxysilane (TEOS) and then with tetrapropylammonium hydroxide (TPAOH). After crystallization and calcination, the silicalite-1...
