The synthesis and characterization of silicalite-1 made in reverse micelle at 433k are reported. Silicalite-1 materials formed in reverse micelle synthesis possessed different shapes compared to those formed by conventional methods. Syntheses were also performed to ascertain how the content of surfactant and heptane, silica source and NaOH content influence material properties. The current work showed that the morphology of the crystals obtained was highly sensitive to surfactant and heptane content and silica source, but insensitive to the NaOH content. Silicalite-1 materials that were coffin, hexagonal prismatic and rod shapes could be obtained in the present of reverse micelle.
