Enhancing electrostatic interactions to activate polar molecules: ammonia borane methanolysis on a Cu/CoIJOH)2 nanohybrid Chen, Qian-Qian Li, Qiang Hou, Chun-Chao Wang, Chuan-Jun Peng, Cheng-Yun López, Núria Chen, Yong 54 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. 2019-04-29 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion http://hdl.handle.net/2072/359793 https://doi.org/10.1039/C9CY00584F 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/ info:eu-repo/semantics/openAccess 2828 p. application/pdf RECERCAT (Dipòsit de la Recerca de Catalunya)
