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. http://hdl.handle.net/2072/359793 https://doi.org/10.1039/C9CY00584F Enhancing electrostatic interactions to activate polar molecules: ammonia borane methanolysis on a Cu/CoIJOH)2 nanohybrid
