Hydrothermal-treated Pt/Al2O3 as an excellent catalyst for toluene total oxidation
文献摘要:
The preparation of highly active supported noble metal catalysts with a low noble metal loading has always been the ultimate goal of researchers working on catalysis.Hydrother-mally treated Pt/Al2O3(Pt/Al2O3-H)exhibits better catalytic activity than that(Pt/Al2O3-C)treated via the conventional calcination approach.At the high space velocity of 100,000 mL/(g·hr),the temperature that correspond to 50%toluene conversion(T50)of Pt/Al2O3-H is 115℃lower than that of Pt/Al2O3-C,and the turnover frequency(TOF)value can reach 0.0756 sec-1.The mechanism by which the hydrothermal approach enhances Pt/Al2O3 activity has been investigated.The structure associated with the high catalytic ac-tivity of Pt nanoparticles(NPs)can be retained via hydrothermal treatment.Furthermore,the support is transformed to AlO(OH)with numerous surface hydroxyl groups,which in turn can facilitate the adsorption of toluene.And the synergistic effects of Pt NPs and AlO(OH)increases the contents of Pt in oxidation state and active oxygen,which are bene-ficial for toluene oxidation.
