Use the metal-organic framework (MOF) as the catalyst for the oxygen reduction reaction (ORR) in alkaline media

MOFs represent a new type of materials, and have recently been under broad exploration ofvarious important applications due to their amenability to rational design for differentfunctionalities at molecular level. Metal organic frameworks (MOF) electrocatalysts for theoxygen reduction reaction (ORR) were synthesized by a hydrothermal process using cobaltsalts as the metal ion precursors, The results demonstrate that the as-prepared MOF has agood crystalline structure with abundant micropores,a high specific surface area and a highthermal stability. MOFs exhibits excellent bifunctional catalytic activities for ORR [1]In this work we composite MOF with CNT (50%w/w) and treatment in the Ar furnace with2°C slope until 500°C and 800°C.
