PHC4 exhibits a high CO₂ adsorption capacity at 0 °C/1 bar (3.5 mmol g⁻¹) and 0 °C/30 bar (15.8 mmol  g⁻¹). Additionally, the presence of heteroatoms on the surface results in enhancement of interactions between CO₂ and the adsorbents which are evident from a high value of isosteric heat of adsorption (∼35 kJ mol⁻¹) calculated using Clausius Clapeyron's equation. The reported activation synthesis strategy could be explored further to devise advanced functional nanomaterials for specific adsorption applications.]]> Thu 22 Jun 2023 10:25:37 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43360 Thu 15 Sep 2022 15:47:17 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51761 Mon 18 Sep 2023 14:22:48 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40428 2 capture. The materials are synthesized using KOH activation at 800 °C and show a high content of micropores and high specific surface areas which can be easily manipulated by varying the amount of KOH. The optimized material PAB3 obtained using KOH/grape marc biochar ratio of 3 displays the highest specific surface area (2473 m² g⁻¹), high micropore volume (0.72 cm³ g⁻¹) and a pore diameter of 0.74 nm. Owing to its highly developed porosity and excellent textural parameters, PAB3 exhibits a high CO₂ adsorption of 6.2 mmol g⁻¹ at 0 °C/1 bar and 26.8 mmol g⁻¹ at 0 °C/30 bar. It is often considered challenging to synthesize a CO₂ adsorbent with all-round performance for CO₂ capture under diverse conditions of temperature and pressure. The optimized material PAB3 is also found to be thermally stable which when coupled with its superior CO₂ capture performance presents a promising candidature in the field of carbon capture. Furthermore, the excellent features of the synthesized material suggest that these materials could be extended to several other adsorption related fields.]]> Fri 22 Jul 2022 14:30:25 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51753 Fri 15 Sep 2023 18:27:52 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51354 Fri 01 Sep 2023 13:44:28 AEST ]]>
