Abstract
Formic acid(FA),which is obtainable through CO2 hydrogenation with green hydrogen or biomass con-version,has been used as a prospective liquid organic hydrogen carrier(LOHC)because of the abundant advantages of renewability,wide availability,stability,and high volumetric capacity(53g H2/L).The de-velopment of highly efficient catalytic systems to achieve enhanced catalytic activity is attractive but still challenging.Herein,ultrafine and highly dispersed PdAu nanoclusters(NCs)anchored on amino-modified reduced graphene oxide(ArGO)were successfully synthesized via a facile impregnation-reduction method and applied as a catalyst toward formic acid dehydrogenation(FAD).Benefiting from the promoting ef-fect of amino groups,the strain and ligand effect in the alloy,and the Mott-Schottky effect between PdAu NCs and ArGO,the resultant PdAu/ArGO affords an ultrahigh activity under visible light irradiation with an exceptional turnover frequency value of 10,699.5h-1 at 298 K without any additives,more than 2.6 times improvement than that under dark,which is the highest among all reported catalysts under the same conditions.This study provides a green and convenient strategy for developing more efficient and sustainable FAD catalysts and promotes the effective utilization of FA as a prospective renewable LOHC.
