Reusable catalyst could be a game-changer for the biomass industry

Known for their outstanding versatility, primary amines (derivatives of ammonia) are industrially important compounds used in the preparation of a wide range of dyes, detergents and medicines. Although many attempts have been made to improve their synthesis using catalysts containing nickel, palladium and platinum, for example, few have succeeded in reducing the formation of secondary and tertiary amines and other undesired by-products.

Now, researchers at Tokyo Institute of Technology (Tokyo Tech) have developed a highly selective catalyst consisting of ruthenium nanoparticles supported on niobium pentoxide (Ru/Nb2O5). In a study published in the Journal of the American Chemical Society, the team demonstrated that Ru/Nb2O5 is capable of producing primary amines from carbonyl compounds with ammonia (NH3) and dihydrogen (H2), with negligible formation of by-products.

By pushing the boundaries of material design, the researchers say that Ru/Nb2O5 may accelerate the production of environmentally friendly plastics, rubber and heat-resistant aramid fibers. In future, the Ru/Nb2O5 catalyst may also impact the development of novel anti-cancer drugs, anti-bacterials, pesticides, agrochemicals, fertilizers, bio-oils and biofuels.
