Direct synthesis of organic salt-derived porous carbons for enhanced CO₂ and methane storage

Abstract

The direct carbonisation of a carbon-rich organic salt, Potassium phthalimide (PPI), generates porous carbons with porosity suitable for energy-related gas storage applications. The PPI-derived carbons exhibit high surface area of...

An Ultramicroporous Graphene-Based 3D Structure Derived from Cellulose-Based Biomass for High-Performance CO2 Capture

“…The findings from the Act. 1000 sample displayed a 1.5-fold enhancement at 298.15 K under pressures of up to 110 kPa, when contrasted with the outcomes documented in earlier studies. − The Nelder–Mead pattern search method was utilized to determine the optimal parameter values. The goodness of fit for the experimental data was evaluated by comparing the coefficient of determination ( R 2 , eq ) and average relative error (ARE, eq ) to discern the best fitting model.…”

Porous carbon composites as clean energy materials with extraordinary methane storage capacity

“…21 The excess uptake at 35 bar is 8.5–10.8 mmol g −1 , and is comparable to that of the best carbon or MOF materials reported to date. 12,13,16–18,59–61 The excess uptake increases to between 10.3 and 12.7 mmol g −1 at 65 bar, and reaches a high of 13.4 mmol g −1 for sample CPET4800 at 100 bar.…”

Ultra-high surface area ionic-liquid-derived carbons that meet both gravimetric and volumetric methane storage targets

“…We have previously reported on carbons that have higher volumetric uptake than the IL-ACxT samples but with lower gravimetric uptake that does not reach the DOE target of 0.5 g g À1 . 13,14,47,77 The best performance to date in terms of volumetric methane uptake at 25 1C and 100 bar is for compacted activated carbons derived from clove hydrochar (CHCC2800, CHCC4700 and CHCC4800) at 339, 334 and 309 cm 3 (STP) cm À3 , respectively. 47 However, the overall performance of these clove-derived carbons is limited by their moderate gravimetric uptake.…”
