Highly dispersed nickel anchored on a N-doped carbon molecular sieve derived from metal–organic frameworks for efficient hydrodeoxygenation in the aqueous phase

Abstract

ZIF-8 was employed as a template to synthesize HD-Ni/N-CMS containing highly dispersed Ni at the atomic level anchored on a N-doped carbon molecular sieve for vanillin hydrodeoxygenation. The ZIF-8 structure was inherited and Ni–N bonds were formed by the coordination of Ni with N-rich defects, therefore it exhibited a high turnover frequency (1047.1 h⁻¹) and good stability.
