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 ]]> Pure and strontium carbonate nanoparticles functionalized microporous carbons with high specific surface areas derived from chitosan for CO2 adsorption https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46157 2 g⁻¹). The optimized material exhibits a high surface area of 2278m² g⁻¹ and a pore volume of 1.00 cm³ g⁻¹. As high microporosity is beneficial for CO₂ adsorption, the prepared materials are employed as adsorbents for the capture of CO₂. The optimized sample displays excellent CO₂ uptakes at 0 °C/0.15 bar (1.1–1.8 mmol g⁻¹) and 0 °C/1 bar (4.3–6.1 mmol g⁻¹). The high surface area of the materials allows for high CO₂ uptakes at 0 °C/30 bar (17.3–22.0 mmol g⁻¹). The microporosity of these high surface area carbons is further decorated with strontium carbonate nanoparticles. The adsorption capacity per unit surface area is increased significantly upon the incorporation of the nanoparticles, revealing the role of the nanoparticles on the enhancement of the CO₂ adsorption capacity. A similar strategy could be extended for the fabrication of a series of microporous carbons derived from biomass for many applications including CO₂ capture.]]> Fri 11 Nov 2022 19:13:04 AEDT ]]>
