Nanodiamond Films for Applications in Electrochemical Systems

Abstract

The purpose of the present paper is to give an overview on the current development status of nanocrystalline diamond electrodes for electrochemical applications. Firstly, we describe a brief comparison between the general properties of nanocrystalline diamond (undoped and boron-doped) and boron-doped microcrystalline diamond films. This is followed by a summary of the nanodiamond preparation methods. Finally, we present a discussion about the undoped and boron-doped nanocrystalline diamond and their characteristics, electrochemical properties, and practical applications.

RETRACTED: Application of the HFCVD technique for growth of nano-rods and nano-crystals

“…The formation of sp 2 hybridized aromatic C rings and localized amorphization in B 13 C 2 can be evidently deduced from the development of these peaks for all types of samples. Further, a higher level of structural damage or amorphization in B 13 C 2 is concluded when more intense G and D peaks are obtained by doping boron [47][48][49][50][51][52]. Fig.…”

High dosage thermoluminescence diamond dosimeters

“…Raman spectroscopy allows one to perceive between different phases of a given material, since the Raman scattering efficiency for graphite is over 50 times greater than that for diamond. Figure 2 shows microRaman spectrum of a nanodiamond film with its sharp band located close to 1332 cm -1 , which is characteristic of a good quality diamond [11]. Diamond films exposed at 90 Sr beta radiation at an absorbed dose of 500 Gy show a glow curve with one peak at 440 K, as displayed in Fig.…”

Diamond Coated LW-SAW Sensors-Study of Diamond Thickness Effect

“…No significant fraction of sp 2 carbon phase is observed. The peak at 1490 cm −1 is attributed to transpolyacetylene [7]. On Raman spectra for 30 nm thick NCD layer, one can observe SiO2 substrate's peaks at 800 and 1100 cm −1 .…”
