Abstract

The present study reports the synthesis of a porous Fe-based MOF named MIL-100(Fe) by a modified hydrothermal method without the HF process. The synthesis gave a high surface area with the specific surface area calculated to be 2551 m2 g–1 and a pore volume of 1.407 cm3 g–1 with an average pore size...
