摘要：

A universal and simple one-step approach to fabricate threedimensional (3D) graphene materials with the aid of 1, 2-epoxy propane (PO) has been reported in this paper. PO, as one of widely used engineering materials, is easy to produce ringopening reaction under acidic conditions. When PO is introduced into graphene oxide (GO) dispersion (pH= 2.4-3.8), a 3D graphene architecture will be formed through the reaction of PO with oxygen-containing functional groups (i.e. epoxy, carbonyl and carboxyl groups) on the surface of GO sheets. The obtained 3D graphene monolithic exhibits high porosity, strong mechanical performance, and good adsorption capacities for oil and organic dyes, which may find potential applications in wastewater treatment, environmental remediation, and electrochemistry.
