Ternary CoAgPd Nanoparticles Confined Inside the Pores of MIL-101 as Efficient Catalyst for Dehydrogenation of Formic Acid

Highly dispersed ternary CoAgPd nanoparticles with different composition have been successfully immobilized on the metal-organic frameworks (MIL-101) by using a simple liquid impregnation method for the first time. The molecular scale electronic synergistic effect between non-noble metal Co and AgPd NPs and the confinement effect of MIL-101 are the crucial roles for the improvement of catalytic performances toward dehydrogenation of formic acid under mild conditions. The resultant catalysts are composition dependent toward dehydrogenation of formic acid, while Co9Ag21Pd70@MIL-101 exhibits exceedingly high catalytic activity, with the turnover frequency value of 98 h−1, and 100 % hydrogen selectivity at 50 °C.
