dc.description.abstractTo apply electrically nonconductive metal-organic frameworks (MOFs) in an electrocatalytic oxygen reduction reaction (ORR), we have developed a new method for fabricating various amounts of CuS nanoparticles (nano-CuS) in/on a 3D Cu-MOF, [Cu-3(BTC)(2)(H2O)(3)] (BTC=1,3,5-benzenetricarboxylate). As the amount of nano-CuS increases in the composite, the electrical conductivity increases exponentially by up to circa 10(9)-fold, while porosity decreases, compared with that of the pristine Cu-MOF. The composites, nano-CuS(x wt%)@Cu-BTC, exhibit significantly higher electrocatalytic ORR activities than Cu-BTC or nano-CuS in an alkaline solution. The onset potential, electron transfer number, and kinetic current density increase when the electrical conductivity of the material increases but decrease when the material has a poor porosity, which shows that the two factors should be finely tuned by the amount of nano-CuS for ORR application. Of these materials, CuS(28wt%)@Cu-BTC exhibits the best activity, showing the onset potential of 0.91V vs. RHE, quasi-four-electron transfer pathway, and a kinetic current density of 11.3mAcm(-2) at 0.55V vs. RHE.en_US
