Synthesis of hierarchical porous β-FeOOH catalysts in ionic liquid/water/CH2Cl2 ionogels†
Abstract
The ionic liquid/water/CH2Cl2 ionogels were created for the first time, which were used to synthesize hierarchical porous β-FeOOH catalysts. The pore property and crystallinity could be tuned by the CH2Cl2 content in the ionogels. The as-synthesized β-FeOOH catalysts exhibited very high activity and stability for oxidation of benzylic carbons.
