Copper phyllosilicates-derived catalysts in the production of alcohols from hydrogenation of carboxylates, carboxylic acids, carbonates, formyls, and co2: A review

Copper phyllosilicates-derived catalysts (CuPS-cats) have been intensively explored in the past two decades due to their promising activity in carbonyls hydrogenation. However, CuPS-cats have not been completely reviewed. This paper focuses on the aspects concerning CuPS-cats from synthesis methods, effects of preparation conditions, and dopant to catalytic applications of CuPS-cats. The applications of CuPS-cats include the hydrogenation of carboxylates, carboxylic acids, car-bonates, formyls, and CO2 to their respective alcohols. Besides, important factors such as the Cu dispersion, Cu⁺ and Cu⁰ surface area, particles size, interaction between Cu and supports and do-pants, morphologies, and spatial effect on catalytic performance of CuPS-cats are discussed. The deactivation and remedial actions to improve the stability of CuPS-cats are summarized. It ends up with the challenges and prospective by using this type of catalyst.
