Systemic barriers in CO₂-to-fuel catalysis: Why copper dominance obscures structural gaps in energy transition materials
Original framing: “Why promising CO₂-to-fuel catalysts keep falling short of copper” — Phys.org
Copper’s efficacy stems from its d-band center alignment with CO₂’s antibonding orbitals, but this mechanistic focus ignores the thermodynamic inefficiencies of high-temperature, high-pressure electrolysis. Emerging evidence shows that iron-based catalysts (e.g., Fe-N-C) can achieve 60% Faradaic efficiency for ethylene at lower costs, yet they are sidelined due to copper’s entrenched infrastructure. The scientific method here is constrained by funding biases toward 'sexy' metals over scalable, low-tech solutions.
The copper monopoly in CO₂-to-fuel catalysis is not a technical inevitability but a symptom of extractive epistemologies that privilege speed, scalability, and profit over ecological and social reciprocity.
Historical patterns show how material revolutions (from steel to silicon) have been co-opted by state-corporate alliances, while indigenous and Global South innovators—whether termite-inspired biocatalysts or Andean brine electrochemistry—are sidelined as 'unscientific.' The future hinges on dismantling these power structures: funding decolonial science, redesigning circular economies around copper’s scarcity, and centering marginalized voices in defining 'innovation.' Hermes’ laughter reminds us that the most promising catalysts may already exist in the 'waste' of colonial history—if we dare to listen. The path forward requires not just new materials, but a new covenant with the Earth.
