Selective electrochemical reduction of carbon dioxide to formic acid using indium–zinc bimetallic nanocrystals
For the electrochemical reduction of CO 2 (CRR) with high selectivity for HCOOH, In–Zn bimetallic nanocrystals (NCs) were synthesized as catalysts by in situ reduction of In 2 O 3 –ZnO NCs with various compositions. All In-containing bimetallic catalysts exhibited excellent selectivity to produce HC...
