Trimetallic NiCoFe-Layered Double Hydroxides Nanosheets Efficient for Oxygen Evolution and Highly Selective Oxidation of Biomass-Derived 5-Hydroxymethylfurfural

Selective conversion of renewable sources is necessary for developing energy generation technology and protecting the environment. Herein, this work reports a one-step controllable synthesis of trimetallic NiCoFe-layered double hydroxides (NiCoFe-LDHs) nanosheets (1.36 nm) for both an efficient oxygen evolution reaction (OER) and highly selective oxidation of biomass-derived 5-hydroxymethylfurfural (HMFOR) into value-added 2,5-furandicarboxylic acid (FDCA). For comparison, two sets of bimetallic NiCo- and NiFe-LDHs were similarly synthesized and evaluated. In the OER process, the optimal NiCoFe-LDHs nanosheets exhibited the lowest necessary overpotential (288 mV) to reach 10 mA cm–2 and the smallest Tafel…
