The electrochemical synthesis of syngas (CO and H2) has garnered considerable attention in the context Fischer–Tropsch (FT) employing thermal catalysts. Nonetheless, need for a novel, cost-effective technique persists. In this investigation, we introduce direct (dEC) approach FT that functions under ambient conditions by utilizing p-block element (Sn In) overlaid Cu electrode. Surface *CO H* species were obtained an electrolytic medium through CO2 + H+ e– → HOOCad (or CO adsorption)...
