Herein, we present the utilization of Ni2+-doped amine-functionalized UiO-66-NH2 metal-organic framework (MOF) nanoparticles deposited onto multi-walled carbon nanotubes (MWCNTs) as a precursor for electrocatalytically active catalyst towards methanol (MeOH) oxidation. The electrode material displayed an onset potential of 0.42 V (vs Hg/HgO) with maximum activity at 1 M MeOH concentration (143 mA.cm− 2 current density at 0.6 V vs Hg/HgO). The catalyst also demonstrated adequate stability, where 93.5% of its current density was retained after performing chronoamperometry for 1 hr.
Herein, we present the utilization of Ni2+-doped, amine-functionalized, UiO-66-NH2 metal–organic framework (MOF) nanoparticles deposited onto multi-walled carbon nanotubes (MWCNTs) as a precursor to generate electrocatalytically active catalyst towards methanol (MeOH) oxidation. The electrode material displayed an onset potential of 0.42 V (vs Hg/HgO) with maximum activity at 1 M MeOH concentration (143 mA/cm2 current density at 0.6 V vs Hg/HgO). The catalyst also demonstrated high stability, retaining 93.5% of its initial activity under continuous electrolysis for 1 h, and 84.1% after 10 h.
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.
