Abstract
Abstract 5‐Hydroxymethylfurfural (HMF) containing C=O, C−O, and furan ring functional groups is an important platform chemical derived from C 6 sugars. The selective hydrogenation of C=O in HMF produces 2,5‐dihydroxymethylfuran (DHMF), which is a potential sustainable substitute for petroleum‐based building blocks. Here, 2,5‐furandicarboxylic acid (H 2 FDC), a promising sustainable alternative to terephthalic acid, was employed as a renewable ligand to synthesize a novel Cu metal‐organic framework (Cu‐FDC). With a polyvinyl pyrrolidone (PVP)‐assisted approach, 2D Cu‐FDC nano‐lamellae of micrometer lateral dimensions and nanometer thickness could be obtained, which could be used as a precursor to fabricate 2D oxygen‐rich carbon nanosheets embedded with Cu nanoparticles (denoted CFP‐300) after a thermal treatment at 300 °C under N 2 atmosphere. The synthesized CFP‐300 exhibited excellent catalytic performance and stability for the selective hydrogenation of HMF to DHMF. These results demonstrated a sustainable route to synthesize efficient catalysts by employing metal–organic frameworks based on renewable ligands.
