Özet
Formic acid (FA) is a crucial liquid H-2 storage material due to its high gravimetric energy density. Therefore, dehydrogenation of FA using catalysts has attracted considerable attention. However, it is still a challenge to find a selective and active catalyst for this reaction. Bimetallic AgPd nanoparticles are well known combination to obtain efficient catalysts for the dehydrogenation of FA. Therefore, many efforts have been devoted on finding suitable supporting materials to increase the efficiency of AgPd NPs in dehydrogenation of FA. In this study, tungsten(VI) oxide, WO3 was used as a supporting material due to its multiple oxidation states which play an important role for obtaining highly efficient catalyst. Herein, bimetallic AgPd nanoparticles supported on WO 3 were successfully prepared. The activity of AgPcl/WO3 catalysts with different Ag loading was tested in dehydrogenation of FA in presence of sodium formate at 50.0 +/- 0.1 degrees C. Ag0.25Pd/WO3 catalyst with a TOF value of 683 h(-1) exhibited high activity in this reaction. In addition, the effect of sodium formate on the decomposition of formic acid was investigated in detail.
