In FAL hydrogenation, the Rh/C catalyst showed a high THFA yield (92%) with 93% selectivity in aqueous media within 12 h, whereas the use of a dimethylacetamide (DMA) solvent system resulted in a 95% THFA yield within 32 h at 30 °C. The study of the effect of the solvent on FAL hydrogenation reveals that polar solvents showed higher THFA yields than a toluene solvent. The Rh/C catalyst used in this study exhibited higher activity compared to Ru/C, Pd/C, Ni/C derived from Ni-based metal-organic framework (Ni-MOF), and Ni-loaded carbon black (Ni/CB) catalysts in FAL-to-THFA hydrogenation. The Rh/C catalyst is characterized in detail using various characterization techniques such as TEM, XRD, N2-adsorption-desorption, XPS, and ICP-OES to understand its physicochemical properties. The Rh/C catalyst shows similar high THFA yields in the recycling experiment of FAL hydrogenation under ambient conditions. ? 2019 The Royal Society of Chemistry. |
