Scientists map roadmap to turn CO₂ waste into profitable products
Researchers have catalogued practical pathways for converting atmospheric carbon dioxide into valuable materials—from fuels and chemicals to graphene and carbon nanotubes. The finding suggests companies could simultaneously reduce emissions and create revenue streams, though significant technical hurdles remain before large-scale commercialization.
Originaltitel: From carbon capture to carbon-based products: A review of CO₂-to-X pathways
<p>The increasing concentration of atmospheric CO₂ has intensified the need for sustainable carbon managementstrategies. This review explores the emerging field of CO₂ utilization, emphasizing the conversion of CO₂ intovalue-added products (CO₂-to-X) and integrating the CO₂-to-carbon pathway. We provide a comprehensiveanalysis of chemical and electrochemical conversion routes, highlighting the thermodynamic, kinetic, andtechnological challenges associated with each approach. The CO₂-to-X pathways encompass fuels, chemicals,polymers, and materials, demonstrating the potential to simultaneously mitigate emissions and generate economic value. Particular attention is given to the CO₂-to-carbon pathway, including the production of solid carbonmaterials such as graphite, carbon nanotubes, and graphene via the Bosch process, which offer high-value applications in energy storage, construction, and advanced manufacturing. By synthesizing recent advances andidentifying gaps in the literature, this paper provides a roadmap for researchers and industry practitioners aimingto transform CO₂ from an environmental liability into a resource. The study underscores the dual potential of CO₂utilization: reducing greenhouse gas emissions while fostering innovative pathways for carbon-based products,thereby contributing to a circular carbon economy.</p>
