Room temperature synthesis and characterizations of CU-MOF using natural polysaccharide as potential organic linker

In this study, copper-based metal-organic framework was successfully synthesized using natural polysaccharide, gum Arabic (gA, Acacia Senegal) as potential organic linker by adopting the synthesis method from Misran et al. with some modifications. The copper-based metal-organic framework (Cu-MOF) wa...
