主 题：Metal-organic frameworks Oxygen evolution Cobalt Iron Electrocatalysts Water oxidation
摘 要：Metal-organic frameworks（MOFs） have been regarded as promising catalyst materials due to the richness of coordinately unsaturated metal sites on the surface,which can act as catalytic active *** this study,a hybrid MOF material composed of Fe-based MOF and Co-based MOF was prepared with the involvement of graphene oxide nanosheets as *** was demonstrated that the hybrid MOF materials showed much higher electro-catalytic activity towards oxygen evolution than the single-phase *** drive current density of 10 mA cm;,the hybrid CoFe-based MOF only needed an over potential of 290 mV in 1 M *** catalytic activity could sustain for a longer time with only slight current density *** oxygen evolution operation,the MOF catalyst evolved into catalytic active species but kept well the microscale sheet-like *** is thus believed that this study will provide an avenue for the development of advanced electrocatalysts.
