Thermally stable proton conductivity from nanodiamond oxide

Herein, we report nanodiamond oxide (NDOx), obtained from modified Hummers' oxidation of nanodiamond (ND), showing excellent proton conductivity and thermal stability. NDOx possesses hydrophilicity resulting in higher water adsorption and the retention of functional groups at elevated temperatures can be attributed to the high proton conductivity and thermal stability, respectively.

Automated summary

In this study, nanodiamond oxide (NDOx) prepared from modified Hummers' oxidation of nanodiamond (ND) is reported to exhibit excellent proton conductivity and thermal stability. The hydrophilicity of NDOx leads to higher water adsorption, while the retention of functional groups at elevated temperatures can be attributed to its high proton conductivity and thermal stability.
