Abstract:
|
Optimization of metal–support interactions (MSIs) is at the core of heterogeneous catalyst design. For polar
reactants, electrostatic interactions resulting from MSIs can facilitate their activation. In this work, a feasible
in situ method has been employed to control the electrostatic properties at the interface of a noblemetal-
free Cu/CoIJOH)2 nanohybrid catalyst. On the Cu/CoIJOH)2 interface, the positively charged copper
enhances the polar molecule adsorption. By varying the metal/support ratio, a highly efficient catalytic activity
for the methanolysis of ammonia borane (AB) with an initial turnover frequency (TOF) of 61.63 mol(H2)
mol(catalyst)
−1 min−1 and long-term stability at ambient temperature were observed. Theoretical analysis unravels
the role of charge transfer in promoting the reactions and the metal/support ratio in manipulating
the catalytic activity via tuning electrostatic interactions. |
