Direct synthesis of ordered mesoporous polymer and carbon materials by a biosourced precursor

Abstract

Ordered mesoporous polymer and carbon materials were prepared with a one-pot green chemistry synthesis using tannin as a biosourced carbon precursor. The process is based on the evaporation-induced self-assembly of the tannin with an amphiphilic surfactant. Tannin self-condensation polymerization reactions were used to avoid any carcinogenic cross-linkers such as formaldehyde and to improve the thermal stability of the intermediate ordered mesophase. The calcinations of the mesophase lead to polymer and carbon materials having a hexagonal array of mesopores beside micropores.
