“…On the other hand, one can expect the formation of a thin water layer on O-DNDs since the oxygenterminated bulk diamond surface is hydrophilic [35]. It was suggested that an ordered water monolayer may exist on other hydrophilic surfaces like mica [36] as well as on the oxygen terminated diamond surface [37]. According to the DSC data (Fig.…”

a b s t r a c tWater interaction with surface modified nanodiamonds (NDs) is critical for many possible applications of NDs e.g. in biomedicine. Here we report on investigation of water interaction with hydrogenated and oxidized detonation nanodiamonds (H-DNDs, O-DNDs) by means of Fourier transform infrared spectroscopy (FTIR), thermal analysis, and Kelvin probe force microscopy (KPFM). Higher water content (4.4%) as well as weaker interaction of water with H-DNDs are identified by thermal analysis. It is explained by hydrophobicity of the H-DND surface, as revealed by the analysis of bending and stretching vibrations of surface water in FTIR spectra. On the other hand, hydrophilic nature of O-DNDs leads to lower water content (3.1%) but stronger interaction with the O-DND surface. This is evidenced by as high as 300°C desorption temperature of the surface water from O-DNDs. KPFM analysis shows that the surface-bound water can have significant screening effect on contact potential difference (CPD) of nanodiamonds (up to 510 mV) as well as on the CPD difference between H-DNDs and O-DNDs (from 50 mV to 210 mV). Nevertheless, H-DNDs exhibit always lower work function.

“…According to this model, a distinct pH sensitivity is expected if surface hydroxyl groups are present on the NCD surface. An existence of hydroxyl groups on the oxidised diamond surfaces has been observed in (Kondo et al, 2005;Theije et al, 2001).…”

“…In the presence of atomic H, reaction heat considerations suggest that the oxygen chemisorbed surface may convert to a more stable hydroxyl terminated C(111)1 × 1 24. de Theije et al 12 found by X‐ray scattering that high oxygen concentration on (111) diamond surface results in nearly full monolayer of OH bonds 12. Experimental results of Loh et al 24 suggest that the exchange of O with preadsorbed D (or vice versa) could proceed on the C(111) surface readily.…”

“…During the last two decades, molecular and activated oxygen (AO) adsorption and desorption phenomena on bare, partially and fully hydrogenated diamond surfaces were investigated both experimentally 12–28 and theoretically 29–32. The majority of this work was performed onto well defined (111), (100), and (110) surfaces, while much less efforts were invested into more common polycrystalline diamond films.…”

In this work the amount of adsorbed oxygen and its chemical bonding configuration to diamond surface were investigated by X‐ray photoelectron spectroscopy (XPS) and high resolution electron energy loss spectroscopy (HR‐EELS), correspondingly. Hot filament chemical vapor deposited polycrystalline diamond films with sub‐micron grain size have been exposed in situ to thermally activated atomic oxygen (AO) and annealed in ultra‐high vacuum (UHV) in the range of 600–1000 °C. XPS studies revealed that substantial oxidation of the diamond surface takes place at TA > 800 °C, most likely owing to partial hydrogen desorption occurring at this temperature. HR‐EELS revealed that the main constituents of the surface after exposure to AO are saturated and unsaturated hydrocarbon species and oxygen‐bonded fragments. Oxygen bonds to diamond surface in ether (COC), peroxide (COOC), and carbonyl (CO) bonding. HR‐EELS features comparison of hydrogenated and oxygen exposed diamond surface as a function of thermal annealing suggests enhanced reactivity of hydrogenated diamond (111) facets as compared to (100) ones.
