“…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.…”

“…In addition to the above‐mentioned oxygen and hydrogen electrode reactions, vacancy engineering has also been applied to other energy‐related applications such as urea oxidation, [ 223 ] hydrogen peroxide production, [ 224 ] methanol oxidation [ 64 ] and others. [ 225 ] For instance, Luo and co‐workers [ 64 ] prepared ultrathin NiO nanosheets with rich oxygen vacancies, resulting in excellent catalytic performance for the methanol oxidation reaction (MOR). Theoretical results demonstrated that the presence of oxygen vacancies can improve the electrical conductivity and optimize the adsorption energy of methanol molecules on the active sites.…”

Efficient electrocatalysts are key requirements for the development of ecofriendly electrochemical energy‐related technologies and devices. It is widely recognized that the introduction of vacancies is becoming an important and valid strategy to promote the electrocatalytic performances of the designed nanomaterials. In this review, the significance of vacancies (i.e., cationic vacancies, anionic vacancies, and mixed vacancies) on the improvement of electrocatalytic performances via three main functionalities, including tuning the electronic structure, regulating the active sites, and improving electrical conductivity, is systematically discussed. Recent achievements in vacancy engineering on various hotspot electrocatalytic processes are comprehensively summarized, with focus on the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), nitrogen reduction reaction (NRR), CO2 reduction reaction (CO2RR), and their further applications in overall water‐splitting and zinc–air battery devices. The recent development of vacancy engineering for other energy‐related applications is also summarized. Finally, the challenges and prospects of vacancy engineering to regulate the electrocatalytic performances of different electrochemical reactions are discussed.

“…In an important demonstration of electrode structure and morphology enhancing the catalytic activity of cobalt oxide (CoO) electrodes, Huang et al. showed that by doping the CoO electrodes with selenium in a 23 : 1 ratio of CoO to trogtalite (CoSe 2 ), HMF oxidation to FDCA could be performed with high selectivity and efficiency [52] . The authors reasoned that this heteroatom doping strategy shown effective in zinc‐air battery electrodes would create more oxygen vacancies for electrochemical oxidation.…”

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.
