Fullerene Crystals with Bimodal Pore Architectures Consisting of Macropores and Mesopores

A new class of fullerene (C-60) crystals with bimodal pore architectures consisting of macropores and mesopores was synthesized by using a liquid-liquid interfacial precipitation (LLIP) method involving an interface between isopropyl alcohol (IPA) and a saturated solution of C-60 in a mixture of benzene and carbon tetrachloride (CCl4). By varying the mixing fraction of CCl4 in benzene, the porosity and electrochemically active surface area can be flexibly controlled.
