5-Hydroxymethylfurfural (HMF), serving as a versatile platform compound bridging biomass resource and the fine chemicals industry, holds significant importance in conversion processes. The electrooxidation of HMF plays crucial role yielding valuable product (2,5-furandicarboxylic acid), which finds important applications antimicrobial agents, pharmaceutical intermediates, polyester synthesis, so on. Defect engineering stands one most effective strategies for precisely synthesizing electrocatalytic materials, could tune electronic structure coordination environment, further altering adsorption energy intermediate species, consequently increasing kinetics electrooxidation. Thereinto, routine defect are anionic vacancies cationic vacancies. In this concise review, catalytic reaction mechanism selective oxidation is first elucidated, with focus on synthesis involving both Recent advancements various systems summarized synthesized from perspective. Finally, future research prospects discussed.

This paper presents a simple and low-cost one-step synthesis method of cobalt molybdates. Several structural, optical catalytic characterization techniques are used in synergy to highlight the properties synthesized material. EDX, FTIR, X-ray diffraction analysis confirmed formation pure β-CoMoO4 phase. The obtained particles polydisperse with quasi-agglomerated nanowires shape diameters estimated range (115 ± 22) nm by atomic force microscopy (AFM). In addition, band gap energy, Eg = 2.81 eV, shows that can absorb near-UV visible therefore act as photocatalyst. A photocatalytic activity against methylene blue (MB) degradation up 52 % was observed under light irradiation. As result, pseudo-first-order kinetic rate constant MB photodegradation, presence nanowires, be 0.013 min−1. photodegradation efficiency material could mainly related positions conduction (ECB 0.23 eV) valence (EVB 3.04 potential energies, which favorable generation reactive oxygen species (ROS). Moreover, sample recovered from solution centrifugation reused three times without significant loss activity. We experimentally prove show strong stability for consecutive cycles.

Abstract Developing a Pd‐based catalyst possessing high efficiency and low mass loading remains big obstacle for the large‐scale application of electrocatalytic hydrodechlorination (EHDC) chlorophenols (CPs). Herein, dispersion Pd nanoparticles imbedded in 2+ hydroxide species are decorated on surface F−Co(OH) 2 nanowire arrays with newly developed electrodeposition hydrolysis coupled process. EHDC 2,4‐dichlorophenol (2,4‐DCP) as‐obtained Pd/F−Co(OH) /NF‐a exhibits superior performance than other control samples this work literature reports. A 100 % removal 2,4‐DCP is accomplished within 120 min, featuring fast reaction kinetics (kobs=5.0×10 −2 min −1 ) activity (MA=22.2 g Pd). Mechanism investigation shows that intentionally introduced sites play pivotal role adsorption 2,4‐DCP, while facilitates generation active H*, thus promoting catalytic performance. This presents valuable example designing high‐performance catalysts by composition tuning.
