Inhomogeneous Hollow and Porous Materials for CO2 Capture, Utilization, and Energy Storage

About this Research Topic

The vast utilization of fossil fuels in modern industries evokes catastrophic climate changes on a global scale, which consequently cause economic, production, and population loss across the world. It is urgent for the industries to reduce CO2 generated by using fuels, which is a major contributor to the greenhouse effect, by either choosing clean energy sources or capturing the emitted CO2. Hollow and porous materials, such as activated carbon, metal organic frameworks, zeolites, hollow CaO microspheres, biomass-derived porous carbons, are utilized to facilitate CO2 capture in power plants via carbon capture and storage technologies (CCS).

However, current CO2 adsorbents suffer from low regeneration efficiency and high energy consumption, which may elevate the operational cost of power plants up to 30%. New designs of porous materials and a deeper understanding of the absorption/adsorption mechanisms are required for the wide-spread applications of CCS. Recently, inhomogeneous and multiphasic hollow and porous materials, i.e., Mxenes, nitrogen and boron doped carbons, metal organic framework-derived carbons, and porous aromatic frameworks, have shown enhanced CO2 capture properties in terms of higher carbonation conversion, lower regeneration energy, and longer cycling life, which may provide in-time solutions for the existing challenges. On the other hand, the captured CO2 can be utilized to facilitate the advanced fabrication of high-surface-area electrocatalysts for metal-air and lithium-ion batteries, e.g., supercritical CO2 assisted synthesis and CO2 reduction. Furthermore, metal-free electrocatalysts based on inhomogeneous hollow and porous materials are emerging as high-performance cathodes for metal-air and metal-CO2 batteries.

This Research Topic is aimed to attract state-of-the-art research on the inhomogeneous hollow and porous materials for CO2 capture, CO2-based synthesis, metal-air and metal-CO2 batteries, which may provide useful insights on the design, fabrication, property characterization, and mechanisms of the emerging porous materials. The scope of this theme collection may include but not limited to the following:
• Mxenes
• Metal organic framework-derived carbons
• Metal-carbon hybrid materials
• Biomass-derived carbons
• Heteroatom-doped carbons
• Graphene-based materials
• Porous aromatic frameworks


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
