Effects of carbonization conditions on the microporous structure and high-pressure methane adsorption behavior of glucose-derived graphene

A simple, promising, environmentally friendly, and high yield technique to synthesize high specific surface area (SSA) and porous graphene-like materials from glucose precursor through carbonization and controlled chemical iron chloride (FeCl3) activation was demonstrated. Designing this nanoporous...
