title: Boron-Functionalized Graphene Oxide-Organic Frameworks for Highly Efficient CO2Capture.
abstract: The capture and storage of CO2have been suggested as an effective strategy to reduce the global emissions of greenhouse gases. Hence, in recent years, many studies have been carried out to develop highly efficient materials for capturing CO2. Until today, different types of porous materials, such as zeolites, porous carbons, N/B-doped porous carbons or metal-organic frameworks (MOFs), have been studied for CO2capture. Herein, the CO2capture performance of new hybrid materials, graphene-organic frameworks (GOFs) is described. The GOFs were synthesized under mild conditions through a solvothermal process using graphene oxide (GO) as a starting material and benzene 1,4-diboronic acid as an organic linker. Interestingly, the obtained GOF shows a high surface area (506 m2g-1) which is around 11 times higher than that of GO (46 m2g-1), indicating that the organic modification on the GO surface is an effective way of preparing a porous structure using GO. Our synthetic approach is quite simple, facile, and fast, compared with many other approaches reported previously. The synthesized GOF exhibits a very large CO2capacity of 4.95 mmol g-1at 298 K (1 bar), which is higher those of other porous materials or carbon-based materials, along with an excellent CO2/N2selectivity of 48.8.
