“…52,53 MOFs and COFs have begun to be used for this reaction but have thus far only been applied in highly alkaline conditions. 37,57 Similarly, high conversion rates and faradaic efficiency values (both above 95%) have been noted for transition metal based catalysts, but only in highly alkaline conditions (0.1 to 1.0 M KOH). [54][55][56][58][59][60][61][62][63][64] As discussed below, we believe that the key to the high performance of this system in weakly basic conditions lies in the unique active site conguration.…”

“…35,36 In the last year, transition metal sites in MOFs explored as active sites for HMF oxidation. 37,38 We moved to systematically study the structure and activity of these missing hydroxyl linker defect NiO 4 sites within Ni-MOF-74 with the aim of generating an in depth understanding of how they function in an electrocatalytic context and by doing so, extract out valuable design principles that can be generalized across a wide array of systems.…”

The development of electrochemical catalytic conversion of 5‐hydroxymethylfurfural (HMF) has recently gained attention as a potentially scalable approach for both oxidation and reduction processes yielding value‐added products. While the possibility of electrocatalytic HMF transformations has been demonstrated, this growing research area is in its initial stages. Additionally, its practical applications remain limited due to low catalytic activity and product selectivity. Understanding the catalytic processes and design of electrocatalysts are important in achieving a selective and complete conversion into the desired highly valuable products. In this Minireview, an overview of the most recent status, advances, and challenges of oxidation and reduction processes of HMF was provided. Discussion and summary of voltammetric studies and important reaction factors (e. g., catalyst type, electrode material) were included. Finally, biocatalysts (e. g., enzymes, whole cells) were introduced for HMF modification, and future opportunities to combine biocatalysts with electrochemical methods for the production of high‐value chemicals from HMF were discussed.

“…In addition, bionic principles entail utilization of the structural features of some oxidases or dehydrogenases as inspiration for the design of molecular catalysts. [115] Owing to the high catalytic selectivity of enzymes, the structurally similar molecular catalysts also exhibit high catalytic selectivity. Therefore, molecular catalysts are considered to have numerous application prospects.…”
