Metal-organic frameworks for catalysis and energy
There has been a rapid development in metal-organic frameworks (MOFs), especially porous MOFs, due to their high potential for diverse applications in the past decade, especially for catalysis and energy. Recently, we have successfully synthesized a number of new porous MOFs and found their new applications as catalysts, as supports for metal nanoparticles and as templates/precursors for nanoporous carbon synthesis.1-2 Novel porous metal-organic frameworks have been synthesized, which present stable catalytic activities for the oxidation of CO to CO2. Metal nanoparticles (NPs) have been immobilized to MOFs by the solid-grinding method, impregnation method and double-solvents approach in combination with the H2 reduction, liquid-phase concentration-controlled reduction and the CO-directed reduction at the solid-gas interface, which exhibit excellent catalytic performances for various reactions, including hydrogen generation from chemical hydrides. “Quasi-MOFs” have been prepared by controlled deligandation of MOFs, which have a transition-state structure between the porous MOFs and metal oxides. The metal cluster/quasi-MOF composites not only retain a porous structure but also achieve a strong interaction between the metal clusters (eg, Au) and the inorganic nodes (eg, Cr–O) of the quasi-MOF, leading to dramatically enhanced catalytic performance in the low-temperature oxidation of carbon monoxide (CO). Porous carbons have been synthesized by using MOFs as templates/precursors and the resultant carbons display high specific surface areas and excellent electrochemical properties as electrode materials for electric double-layered capacitor (EDLC) and as catalysts for oxygen reduction reaction (ORR). This talk will discuss the catalytic and energy applications of MOFs.
