摘      要：Recycling performance of heterogeneous catalysts is of crucial importance especially for a batch reaction *** this work,we demonstrate a strategy for enhancing recycling performance of Ir-Re/SiO_(2) catalyst synergized with amberlyst-15 in glycerol hydrogenolysis to produce 1,*** characterization results reveal that the Re sites in the Ir-Re/SiO_(2) catalyst undergo irreversible segregation and *** hinder the formation of active ReAOH species and thus contribute to a complete and irreversible ***,the introduction of amberlyst-15 into the reactant mixture can restrain the oxidation process of Re sites and favor the formation of ReAOH species,and thus significantly enhance the catalytic recycling *** results demonstrated here could guide the development of excellent bimetallic catalysts with the desirable recycling performances for the reaction.
