Abstract
- Here we report for the first time a Pd-MnO<subscript>2</subscript> catalyst with a single-atom feature that can convert 5-hydroxylmethyfurfural (HMF) into the important bioplastic building block 2,5-furandicarboxylic acid (FDCA) with a high yield of 88% in aqueous solution using O<subscript>2</subscript> as an oxidant at ambient pressure. Pd-MnO<subscript>2</subscript> shows higher activity in the productivity of FDCA (100.91 mmol h<superscript>−1</superscript> g<subscript>Pd</subscript><superscript>−1</superscript>) than its Pd nanoparticle counterpart (45.57 mmol h<superscript>−1</superscript> g<subscript>Pd</subscript><superscript>−1</superscript>) and state-of-the-art Pd-based catalysts. Pd-MnO<subscript>2</subscript> displays promising recyclability with no degradation after five catalytic runs. Experimental and theoretical results suggest that the single-atom Pd sites that have enhanced binding affinity to HMF and their surrounding sites on the MnO<subscript>2</subscript> support work synergistically toward HMF oxidation.
