It has been proposed that metal cyanide complexes would have acted as effective prebiotic catalysts. Insoluble metal cyanide complexes could have concentrated biomonomers from the dilute prebiotic soup, facilitating certain prebiotic reactions. In the light of the above hypothesis, interaction

Electrolytic water splitting using surplus electricity represents one of the most cost-effective and promising strategies for hydrogen production. The high overpotential of the oxygen-evolution reaction (OER) caused by the multi-electron transfer process with a high chemical energy barrier, however, limits
