Carbon Dioxide Capture or Removal and Valorisation: Advances in the Development of Materials and Technologies

Topic Information

Dear Colleagues,

The energetic transition requires the replacement of fossil fuels with renewable energy sources, along with the development of innovative decarbonation technologies and the establishment of a circular economy model. Developing and deploying carbon capture (from fixed sources) or removal (from the atmosphere) technologies using innovative CO₂ capture materials and CO₂ valorization in short- or long-lived biofuels or green products are essential to reach carbon neutrality or negative emissions targets. This Special Topic, “Carbon Dioxide Capture or Removal and Valorisation: Advances in the Development of Materials and Technologies”, will address topics related, but not limited to:

• Advances in CO₂ sorbent properties for carbon removal (e.g., direct air capture, mineralization, biochar) and capture (e.g., post-combustion and pre-combustion conditions);
• Enhancement of natural and synthetic sorbent materials properties for CO₂ uptake;
• Stability, activity, and regeneration of sorbents under different technological applications at low, medium, or high temperatures;
• Dual-function materials for CO₂ capture and conversion;
• Development of catalysts for CO₂ conversion to biofuels and green products;
• Thermal-, photo-, electro-, bio- and plasma catalysis applications in CO₂ conversion;
• Carbon capture from power plants and industrial sectors and carbon removal from the air—novel technologies, integrated concepts, and methodologies;
• Conversion of CO₂ into fuels and chemicals through biological, thermal, electrochemical, and photochemical processes. In this topic, original papers or reviews are welcome.

Traditional methods to develop biomass-based carbon adsorbents generally involve carbonization followed by chemical or physical activation. However, routes involving the hydrothermal treatment of biomass are receiving growing interest. In this work, two different strategies for the synthesis of sustainable CO₂ adsorbents are compared, i.e., in situ ionic activation and hydrothermal treatment followed by activation with CO₂. The latter is a green and simple procedure that does not require the addition of chemicals or acid-washing stages, and which leads to carbon adsorbents with relatively high CO₂ adsorption capacity at low pressures, up to 0.64 mmol g⁻¹ at 15 kPa and 50 °C, conditions relevant for postcombustion CO₂ capture applications. On the other hand, in situ ionic activation can lead to carbon adsorbents with superior CO₂ adsorption capacity in the aforementioned conditions, 0.78 mmol g⁻¹, and with reduced cost and environmental impact compared to conventional chemical activation.
