Interfacial Engineering Enables Highly Efficient CO2/H2O Co-electrolysis for Syngas Production.
Electrochemical co-electrolysis of CO2 and H2O in solid oxide electrolysis cells (SOECs) provides a promising pathway toward carbon-neutral fuel production and renewable energy storage, yet its efficiency and selectivity remain constrained by the limited reactivity of conventional cathodes. Here, we develop a CeO2/Ni-Y...
