Abstract:
Recently, we have successfully synthesized a number of porous MOFs and developed their new applications as catalysts, as supports for metal nanoparticles and as templates/precursors for synthesis of nanostructured materials.1, 2 Porous carbons and carbon composite materials have been synthesized by using MOFs as templates/precursors and the resultant materials display high specific surface areas and excellent electrochemical properties as electrode materials for electric double-layered capacitor (EDLC) and as electrocatalysts for various reactions. Super-long single-crystal cobalt-organic framework (Co-MOF) nanotubes have been synthesized and carbonized to produce hierarchical dendrites with carbon nanofiber trunks and carbon nanotube branches, which exhibit excellent electrocatalytic activity for oxygen reduction reaction (ORR), and exceptional applications in rechargeable Zn–air batteries. A single-crystal capsular-MOF with openings on the wall has been synthesized, which can easily load the largest amounts of sulfur and iodine among known MOFs. Derived from capsular-MOF and melamine through pyrolysis−phosphidation, we fabricated a nitrogen-doped capsular carbon-based framework with iron−nickel phosphide nanoparticles immobilized on capsular carbons interconnected by plentiful carbon nanotubes, which exhibits efficient multifunctional electrocatalysis for oxygen evolution (OER), hydrogen evolution (HER), and oxygen reduction (ORR), achieving well-qualified assemblies of an overall water splitting and a rechargeable Zn−air battery. “Quasi-MOFs” have been prepared by controlled deligandation of MOFs, which have a transition-state structure between porous MOFs and metal oxides and exhibit dramatically enhanced catalytic performance. This talk will discuss the catalytic and energy applications of MOF-derived nanomaterials.
