英文摘要: Various graphene derivatives have been extensively synthesized and used in several research areas. Currently, however, very few examples of graphene derivatives that exhibit mesoporosity have been reported. In this work, we describe a facile method based on a self-assembly process of two-dimensional (2D) graphene oxides in aqueous solutions to produce three-dimensional (3D) mesoporous graphene oxide (MEGO) solids. The resulting MEGO solids exhibit exceptionally narrow mesopore distributions (2.4 nm), high surface areas, large pore volumes and high thermal stabilities (>450 °C). The MEGOs were used as adsorbents for CO2 and CH4; they showed good adsorption performance, particularly for CO2 at high pressures and remarkable recyclability, suggesting this material is a potential candidate to be used as adsorbent in precombustion process. © 2017 Elsevier Ltd. 资助项目: Conselho Nacional de Desenvolvimento Científico e Tecnológico
