Influence of post-synthetic graphene oxide (GO) functionalization on the selective CO2/CH4 adsorption behavior of MOF-200 at different temperatures; an experimental and adsorption isotherms study

In this work, a metal-organic framework (MOF-200) demonstrating microporosity was prepared from organic linker 1,3,5-tris(4-carboxy1,2-biphenyl-4-yl)-benzene) (H3BBC) and salt Zinc Nitrate Hexahydrate (Zn-(NO3)2·6H2O) via direct solution-based and catalyst-free method. The MOF-200 was further post-...
