Article Synopsis
- Researchers have created highly microporous carbons from pistachio shells, achieving high surface areas (up to 3300 m²/g) and pore volumes using a CO2 activation process.
- Different methods were tested to transform the biomass into carbon materials with varying structures and reactivities towards CO2, while optimizing pore development.
- The most effective technique involved hydrothermal carbonization, which boosts carbon yield and porosity, and higher activation temperatures can speed up the process without losing pore quality.
Cork-Derived Carbon Sheets for High-Performance Na-Ion Capacitors.
ACS Appl Energy Mater
August 2023
S-doped carbon sheets have been easily prepared by deconstructing the 3D cellular structure of a fully sustainable and renewable biomass material such as cork through a mild ball-milling process. S-doping of the material (>14 wt % S) has been achieved by using sulfur as an earth-abundant, cost-effective, and environmentally benign S-dopant. Such synthesized materials provide large Na storage capacities in the range of 300-550 mAh g at 0.
