Developing non-noble metal catalysts for methanol oxidation in fuel cells is of importance. In this work, Ni-MOF-74 was synthesized through a simple solvothermal method and fully characterized. The as-made Ni-MOF-74 modified carbon paste electrode (Ni-MOF-74/CPE) was applied for methanol electrooxidation reaction in 0.1 M NaOH solution. Ni-MOF-74 had high electrochemical stability and exhibited good electrocatalytic property for methanol oxidation, a mechanism for the reaction was proposed, the current density increases impressively on Ni-MOF-74/CPE compared with carbon paste electrode, and a really high catalytic rate constant (k cat ) of 8.1 × 10 5 cm 3 • mol À 1 • s À 1 was obtained in this work. The given results indicate that Ni-MOF-74 can be a promising candidate of electrocatalysts for direct methanol fuel cells (DMFCs).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
