Abstract

Deformed orthorhombic niobium oxide-supported Au nanoparticles (Au/Nb₂O₅-DO) exhibited high catalytic activity for N-formylation of amines using CO₂ and H₂ compared to other Au/Nb₂O₅ catalysts having different crystalline structures. Au/ Nb₂O₅-DO also showed high selectivity to methyl formate in CO₂ hydrogenation. Nb₂O₅-DO possessed a greater amount of acid sites than Au/Nb₂O₅-T (orthorhombic) and Au/Nb₂O₅-A (amorphous), which would be beneficial for formate activation and amine adsorption.
