Five-metal 2D catalysts could convert CO₂ to CO without needing an extra electrical boost

Carbon dioxide (CO₂) has long been framed as a pollutant to be eliminated, with emissions from fossil‑fuel combustion for electricity, transportation and industry contributing the bulk of the gas that accumulates in the atmosphere. The prevailing narrative links rising CO₂ levels to the climate crisis, prompting governments and companies to set targets for reduction and removal.

A growing body of research now examines whether the same CO₂ can be captured and repurposed, turning a climate‑change driver into a feedstock for industrial processes. Scientists are developing technologies that convert captured CO₂ into chemicals, fuels, building materials and other products, thereby creating a circular carbon loop that could lower net emissions while supplying raw materials. Early pilot projects and laboratory studies suggest that, with sufficient scale and economic viability, such carbon‑utilisation pathways could complement traditional mitigation strategies and re‑integrate CO₂ into the manufacturing cycle.
