DOI: 10.1021/acssuschemeng.8b03528
Abstract: A versatile precursor of protic ionic liquids ([Megl][HSO4]) was used to prepare N/S-codoped hierarchically porous carbon materials (N/S-HPC) by a double soft-template solvent-free self-assembly method. [Megl][HSO4] as carbon source, heteroatoms source and microporous forming agent,… read more here.
