MOFs, or metal-organic frameworks, are a class of materials known for their diversity and high surface area. Recently, conductive MOFs have gained a lot of attention, since they can transport both ions and electrons. Such well-ordered, porous, conductive materials are promising for future applications as electrodes that don't suffer from material fatigue and other current issues. Making a conductive MOF (Fe(1,2,3--triazolate)2) as nanoparticles made the material easy to process, and we could also study its size-dependent properties. Because the pores of the material are very small, the ability of iron atoms within the particles to gain or lose electrons depends on the size of the ions used. Finally, it was found that smaller particles show improved electrical conductivity.
Thank you for watching!
