Bifunctional catalysts of Ni nanoparticle coupled MoO₂nanorods for overall water splitting

Abstract

The development of active and cost-effective bifunctional catalyst is crucial for water dissociation through electrolysis. In this study, bifunctional catalysts with Ni nanoparticles (NPs) anchored on MoO2 nanorods have been...

CuCo Nanoparticle, Pd(II), and l-Proline Trifunctionalized UiO-67 Catalyst for Three-Step Sequential Asymmetric Reactions

“…The combination and cooperation of two or more of such active sites, which are spatially distributed in MOFs, promote MOFs to be promising multifunctional catalysts for multi-step sequential reactions. Unfortunately, MOF-based heterogeneous catalysts have only focused on one or two catalytic sites, − being applied in one-step or two-step reactions, and trifunctional catalysts are seldom reported, , such as Pd@HPW@HP-UiO-66-NH 2 with three active sites (amino, Pd nanoparticles, and phosphotungstic acid (HPW)) for three-step deacetalization–Knoevenagel–hydrogenation reactions in which amino groups came from the ligand, 2-aminoterephthalic acid, Pd was embedded in the cavities of MOFs and HPW was linked to the NH 2 group of the ligand; a trifunctional MOF (MIL-IMAc-Br – ) with carboxylic acid groups, Br – anions, and coordinatively unsaturated metal sites as Brønsted acid sites, nucleophilic sites, and Lewis acid centers, respectively, which was further applied to CO 2 cycloaddition reaction …”
