Initial findings suggest that approximately 50 wt% of graphite experiences interlayer expansion. The conventional d spacing of 0.34 nm is modified to a range of intervals between 0.41 nm and 1.22 nm. As a consequence of high operational temperature (800 °C), cations (Li⁺, Na⁺ and K⁺) as well as potentially the anion (CO₃²–) intercalate between graphitic layers and overcome Van der Waal force between layers. Employing a pressurized N₂ environment of 5 bar and 10 bar successfully controls carbonate vaporization and decomposition, as well as inducing ordered layer manipulation to exfoliate more graphite planes from the edges towards deeper levels of the particles. Exploring parameters of both carbonate loading and treatment time in addition to pressure demonstrate that this work opens up a rich selection of parameters that can be used to produce carbons with tuned properties from graphite.]]> Tue 25 Jul 2023 17:58:35 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54173 Fri 09 Feb 2024 14:23:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40340 Fri 08 Jul 2022 10:26:31 AEST ]]>
