Effect of Synthesis Methods Using Renewable PODFA on Structural Characteristics of Metal-Organic Framework (MOF-5)

Abstract

In this work, metal-organic framework (MOF-5) syntheses were successfully synthesized with three different methods namely i) modified direct-mixing method ii) microwave assisted method and iii) autoclave assisted method without using surfactants. Palm oil derived fatty alcohol (PODFA), dodecyl alcohol (C8) was used as renewable non-surfactant template. Four prominent peaks were observed in all three samples attributable to the reflection planes of (200), (220), (400) and (420) of a cubic structure at ca. 2θ = 6.9°, 9.6°, 13.7° and 15.2°. The morphology of MOF-5 produced using modified direct-mixing method was faceted structure with average size of ca. 1 μm. In addition, the morphology of MOF-5 produced using microwave assisted synthesis was cubic structure with average size of ca. 8.34 μm. However, the morphology of MOF-5 using autoclave assisted method was interpenetrated cubic with average size of ca. 22.65 μm.
