“…In comparison to EDX, CHNS and ICP-OES analyses are more adequate for quantitative chemical analysis; therefore, an oxygen content of 4.77 mass% was determined using the total mass of materials minus the detected elements of the CHNS and ICP-OES analysis. These values are in good agreement with the recent literature [31,32,[59][60][61][62][63]. It is expected that the detected oxygen and hydrogen atoms mostly belong to surface functionalities like carboxylic, ketonic, or hydroxylic groups [40].…”

“…The latter is also causing particle agglomeration forming entities of up to more than 100 nm [31]. Chemically, detonation ND consist out of 80-90 mass% of carbon, a few mass% of oxygen, hydrogen, nitrogen partially located in the core and coming from particle stabilizing functional groups, and possibly minor metal impurities [7,30,32].…”

Rapid sol–gel synthesis of nanodiamond aerogel

The rapid sol-gel synthesis of macroscopic quantities of nanodiamond aerogel (NDAG) is reported at standard temperature and pressure using acid-catalyzed covalent crosslinking of air-oxidized detonation nanodiamond (DND) nanocrystals. Acetonitrile acts as a polar, aprotic solvent both to form a colloidal dispersion of DND particles and to conduct acid-catalyzed polycondensation reactions between resorcinol and formaldehyde (RF) small molecule precursors. Several characterization techniques show that nanodiamond grains are connected via covalent bonding with RF molecules to form a porous, three-dimensional network. Solvent exchange into liquid carbon dioxide and subsequent supercritical drying of NDAGs are used to recover low-density (151 mg/cm 3 ), three-dimensional monolithic aerogels that exhibit surface areas in excess of 589 m 2 /g. The large accessible pore volume from the rapidly synthesized, macroscopic NDAG materials suggests a range of potential applications in catalysis, sensing, energy storage, as well as inert excipients for small-molecule pharmaceuticals.

“…Clearly, the need for stringent characterization has not gone unnoticed by the field, as recent works from Volkov [78], Nesterenko [79], and Singh [73] have demonstrated the need for and extent of characterization required. Quantification of the sp 2 content is of very high importance for a number of applications, but the use of Raman can be hindered when particles exhibit fluorescence.…”
