Abstract:

Development of heterogeneous catalysts for sustainable synthesis of chemicals is a growing area in catalysis and green-sustainable chemistry. This presentation summarizes our recent studies on the direct synthesis of chemicals from alcohols, nitriles, carboxylic acids, esters, amides, and CO2 and biomass platform compounds using supported transition metal catalysts.

Ni metal nanoparticles loaded on the acid-base bifunctional support (Al2O3) is effective for dehydrogenation of alcohols and synthesis of primary amines from alcohols and ammonia. Lewis acidic oxides-supported Pt catalysts for 1) selective hydrogenation of carboxylic acids to alkanes or 2) esters, 3) reductive amination of levulinic acid to pyrrolidones, 4) hydrogenation of amides to amines and 5) reductive N-methylation of amines by CO2+H2.

CeO2, as an acid-base bifunctional catalyst, is effective for hydration of nitriles to amides in water, one-pot ester synthesis from nitriles and alcohols, one-pot synthesis of N-alkyl amides from nitriles with amines, and synthesis of N-alkyl amides from amides and amines (transamidation) under aqueous or solvent-free conditions. Nb2O5 shows high catalytic activity for four types of amide bond formation reactions.
