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. eng L'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative Commons:http://creativecommons.org/licenses/by-nc-nd/4.0/ Enhancing electrostatic interactions to activate polar molecules: ammonia borane methanolysis on a Cu/CoIJOH)2 nanohybrid info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion URL https://recercat.cat/bitstream/2072/359793/5/c9cy00584f.pdf File MD5 17660a35dd8b01b42cd2e2fae8fdd386 2871562 application/pdf c9cy00584f.pdf URL https://recercat.cat/bitstream/2072/359793/1/c9cy00584f.pdf.txt File MD5 92e0b2753a8bd60449f21ebb722717d2 37435 text/plain c9cy00584f.pdf.txt
