Robust hydrogen production from HCOOH over amino-modified KIT-6-confined Pdlr alloy nanoparticles
文献摘要：
Formic acid(FA),which can be produced via CO2 reduction and biomass conversion,has received ex-tensive interest as a convenient and safe hydrogen carrier due to its wide range of sources,renewable,high hydrogen content(4.4 wt％),and convenient storage/transportation.Designing highly efficient cata-lysts is the main challenge to realize the hydrogen production from FA.In this work,well-dispersed and electron-rich Pdlr alloy nanoparticles with a size of 1.8 nm are confined in amino-modified 3D meso-porous silica KIT-6 and applied as a highly efficient catalyst for robust hydrogen production from FA at ambient temperature.Small PdIr alloy nanoparticles confined by amino-modified KIT-6(PdIr/KIT-6-NH2)lead to better catalytic activity compared to that of Pd/KIT-6-NH2 and PdIr confined by bare KIT-6,achiev-ing a high turnover frequency(TOF)value of 3533 h-1 at ambient temperature(303 K),100％H2 selec-tivity and conversion toward the dehydrogenation of FA,which is comparable to the best heterogeneous catalysts ever reported.The high catalytic activity of PdIr/KIT-6-NH2 can be attributed to the synergistic effect between Pd and Ir,strong interaction between PdIr and KIT-6-NH2,as well as the amino-groups of KIT-6-NH2 which can act as a proton scavenger to promote the breaking of O-H bond of formic acid.
