Implication

Experimental study demonstrates methane and methanol synthesis on seven transition metals, indicating broader chemical pathways for renewable fuel production.

Key Points

To assess electrocatalytic trends in reducing carbon dioxide into methane and methanol across a diverse set of transition metal surfaces at ambient temperature and pressure.
Evaluated electrochemical carbon dioxide conversion using electricity and water inputs across seven transition metals: gold (Au), silver (Ag), zinc (Zn), copper (Cu), nickel (Ni), platinum (Pt), and iron (Fe).
Quantified reaction rates and selectivity for methane and methanol production in the framework of carbon monoxide (CO) binding energies across each metal surface.
All seven transition metals demonstrated the ability to electrocatalytically generate methane or methanol, disproving the prevailing belief that such activity is limited to selected metals.
Catalytic selectivity toward methane or methanol remained low across most of the tested transition metal surfaces despite universally measurable reaction rates.
Reaction rates and selectivity profiles systematically aligned with the binding energy of intermediate carbon monoxide on each respective metal catalyst.
