Self-Assembled Metal Colloid Monolayers: An Approach to SERS Substrates.
R. G. Freeman,Katherine C. Grabar,K J Allison,Robin M. Bright,J A Davis,A P Guthrie,Michael B. Hommer,Michael A. Jackson,Patrick C. Smith,Daniel G. Walter,Michael J. Natan +10 more
TL;DR: On conducting substrates, colloid monolayers are electrochemically addressable and behave like a collection of closely spaced microelectrodes, which suggest a widespread use for metal colloid-based substrates.

Covalent Modification of Carbon Surfaces by Aryl Radicals Generated from the Electrochemical Reduction of Diazonium Salts
Philippe Allongue,Michel Delamar,Bernard Desbat,Olivier Fagebaume,Rachid Hitmi,Jean Pinson,Jean-Michel Saveant +6 more
TL;DR: In this paper, the authors used cyclic voltammetry, X-ray photoelectron spectroscopy, polarization modulation IR reflection absorption spectrograms, Auger spectrographic analysis, and Rutherford backscattering spectrographs to estimate the surface coverage of carbon-epoxy composites.

Electrocatalysis at graphite and carbon nanotube modified electrodes: edge-plane sites and tube ends are the reactive sites
TL;DR: This article overviews recent work in this area which has led it to believe that much of the catalytic activity, electron transfer and chemical reactivity of graphitic carbon electrodes is at surface defect sites, and in particular edge-plane-like defect sites.

Fabrication and evaluation of nanoelectrode ensembles
Vinod P. Menon,Charles R. Martin +1 more
TL;DR: In this article, an electroless deposition procedure for filling the pores in nanoporous filtration membranes with metal (gold) nanowires is described, which allows us to routinely prepare ensembles of gold nanodisk electrodes in which the nanodisks have diameters as small as 10 nm.
Journal ArticleDOI
Investigation of modified basal plane pyrolytic graphite electrodes: definitive evidence for the electrocatalytic properties of the ends of carbon nanotubes.
TL;DR: The basis of the electrocatalytic nature of multi-wall carbon nanotubes is suggested to reside in electron transfer from the ends of nanotube, which structurally resemble the behaviour of edge plane graphite as discussed by the authors.

Ece and disproportionation
TL;DR: In this paper, the effect of the experimental parameters: rate and equilibrium constants, sweep rate and initial concentration can be rationalized with the use of only two dimensionless parameters in the general case.
