Electroless oxidation of diamond surfaces in ceric and ferricyanide solutions: An easy way to produce “C–O” functional groups

“…C-V measurements are very sensitive to surface terminations of diamond [27][28][29][30][31][32]. Usually, oxygen-terminated electrodes exhibit more positive flat band potentials (E FB ) compared to hydrogenterminated ones [27][28][29][30][31].…”

The Use of Conducting Diamond in Electrochemistry

“…Notable work in this area has been primarily carried out by Ramesham [127], Pleskov [31,[128][129][130][131], and Fujishima [132][133][134], using electrodes grown by CVD, HPHT, and from a Ni-Fe-C melt. Most of the work took place over the period 1998-2006.…”

“…For (111) and (100) crystals grown with similar dopant densities, the ET rate for Fe(CN) 6 3−/4− was similar [131]. (iii) The ET rates are faster on a H-terminated semiconducting surface [133] than an O-terminated one [130]. (iv) The rate of ET for Ru(NH 3 ) 6 3+ is faster than Fe(CN) 6 3− for the same crystal faces [131].…”

Characterization of boron doped diamond during oxidation processes: Relationship between electronic structure and electrochemical activity

“…Furthermore, the whole response of the electrode/solution interface may be correlated to the low frequency loop: as the potential is increased the capacitance component increases and, at the higher potential values, the effect of the capacity of the Helmoltz layer can also be included in the response. In such conditions, MS analysis is hardly applicable; indeed, difficulties in the application of this analysis at BDD electrodes are not infrequent [33][34][35][36][37]. In the vicinity of the flat band potential, the capacitance term is extremely sensitive to substrate polarisation due to change in the space charge within the semiconductor.…”

“…Wide-ranging work has been carried out by several research groups, such as those of Swain [1][2][3][4][5], Fujishima [6][7][8][9][10][11][12], Comninellis [12][13][14][15] and Pleskov [16][17][18][19], just to cite some of their more recent papers. Some scientific journals and several congresses have been specifically devoted to the presentation of results obtained, both in basic studies and for possible applications of this material in electroanalytical devices and electrochemical processes [20][21][22][23][24].…”
