Frustrated Lewis pairs engineering on CeO2 to boost BHMF oxidation activity of AuPd for efficient production of FDCA

Interface engineering is a significance strategy to afford efficient selective oxidation for supported catalysts. Herein, constructing of frustrated Lewis pairs (FLPs) sites on CeO₂ and supporting Au-Pd nanoparticles to provide a highly selective production of 2,5-furandicarboxylic acid (FDCA) from 2,5-bis(hydroxymethyl)furan (BHMF). Mechanism investigations illustrate that the FLPs active sites enhance the adsorption and activation of catalyst for BHMF, decreasing the activation energy of rate-determining step. Simultaneously, the FLPs sites induce the electron transfer of 他the catalyst, generating a novel Au-Pd-CeO₂ interface that promotes the adsorption of molecule oxygen and the formation of the superoxide radical. Thereby, the Au_xPd_y/P_T-CeO₂ catalysts enable superior catalytic performance, achieving a satisfactory turnover frequency of 55.29 h⁻¹ and a highly FDCA yield of 94.0 %. Such interfacial FLPs sites exhibit the great potentials for the selective oxidation of various unsaturated compounds.
