Research progress on Pd-based alloy catalysts for hydrogenolysis debenzylation reaction
Hydrogenolysis debenzylation reaction is considered as a key process in organic synthesis field.However,the use of precious Pd metal and its inevitable loss greatly increase the cost of product.Therefore,developing hydrogenolysis catalysts with high performance,long life and low cost is regarded as the core technology to improve the product competitiveness.Among various alternative strate-gies,Pd-based alloy catalysts becomes a more potential scheme due to the synergistic effect,better stability and partial substitution with non-noble metals.Herein,this review summarizes recent progress of Pd-based alloy catalysts for hydrogenolysis debenzylation reaction based on the mechanism,then discusses the design principle,preparation method and alloy effect of Pd-based alloy catalysts.Finally,the design,preparation,application and recycle of Pd-based alloy catalysts are summarized and given an outlook from the perspective of industrialized hydrogenolysis debenzylation reaction.
