Catalytic hydrogenation reaction has become one of the important methods to synthesize high value-added fine chemicals.The hydrogenation reaction is mainly based on metal-supported catalysts,and the commonly used carriers are dominated by metal or non-metal oxides.However,due to the limitations of traditional metal loading and doping methods,there is a lack of effective means to control the site and particle size of active metals in metal-supported catalysts,which greatly limits the application of such catalysts.Molecular sieves are often used as carriers for catalytic hydrogenation because of their unique pore structure,suitable acidity,controllable pore size and surface properties.In the hydrogenation reaction,molecular sieve not only can be a carrier to load active metals but also sometimes can moderately take part in the reaction as an acidic catalyst.These catalysts exhibit excellent catalytic hydrogenation activity and reaction stability.The paper detailedly summarizes the latest research progress in the catalytic hydrogenation of bi-functional catalysts supported by molecular sieves,and mainly introduces the influence of pore structure regulation of molecular sieves,active metal loading method and hydrogenation reaction type on hydrogenation reaction.
