Honeycomb-like lignin-derived carbon (LC) foams doped with reduced graphene oxide (RGO) are fabricated via unidirectional ice-templating followed by freeze-drying and carbonization. The dimensions, constituent contents, and density of the foams could be easily adjusted. By manipulating the density,...
