Electrochemical Cobalt‐Catalyzed C−H Activation

open access: yesChemistry – A European Journal, 2018
AbstractCarbon–heteroatom bonds represent omnipresent structural motifs of the vast majority of functionalized materials and bioactive compounds. C−H activation has emerged as arguably the most efficient strategy to construct C−Het bonds. Despite of major advances, these C−H transformations were largely dominated by precious transition metal catalysts,

Electrochemical Activation of Expanded Graphite Electrode for Electrochemical Capacitor [PDF]

open access: yesJournal of The Electrochemical Society, 2008
An expanded graphite (e-MCMB, mesocarbon microbeads) having a wider interlayer spacing (d 002 = 0.404 nm) than that of common graphites is prepared by heat-treatment of an oxidized MCMB. When the e-MCMB electrode, which gives a negligible capacitance due to a small surface area, is polarized over a certain onset potential [4.6-4.8 V (vs Li/Li + ) for ...
