Hierarchically porous carbons from an emulsion-templated, urea-based deep eutectic

A hierarchically porous carbon monolith (97% porosity) was generated through the carbonization of an emulsion-templated monolith formed from a chain extended, urea-based, deep-eutectic polymer. The highly interconnected micrometer-scale porous structure had a high specific surface area (812 m2 g−1, largely microporous) and exhibited promising results for aqueous solution sorption applications.
