Abstract
Abstract A simple yet efficient one-step route is reported to prepare a three-dimensional interconnected thin-layer carbon network consisting of graphene sheets sandwiched by a porous carbon layer (PCG). Our route relies on the direct pyrolysis of ethylene diamine tetraacetic acid tripotassium salt (EDTA-3K) in the presence of polyelectrolyte-functionalized graphene oxide (GO) at 750
