In the pursuit of high-selective oxidation 5-hydroxymethylfurfural (HMF) to valuable derivatives such as 5-hydroxymethylfuroic acid (HMFCA), 5-formyl-2-furanoic (FFCA), and furan-2,5-dicarboxylic (FDCA), we have developed a diethylenetriamine pentaacetic (DTPA)-assisted strategy construct highly effective photothermal catalyst with maximized Ag–CeO2 interfaces rich oxygen vacancies. Under optimal reaction conditions, this achieves remarkable yields 99% for HMFCA, FFCA turnover frequency (TOF) 163 h–1, 98% FDCA. Combined theoretical calculations series characterization analyses reveal that superior performance is due unique properties vacancies, which enhance electron transport synergistically catalytic activity silver clusters. contrast other photocatalytic systems HMF, work showcases high selectivity in HMF FFCA, These findings not only elucidate mechanisms behind selective but also offer promising approach directional photosynthesis high-purity chemicals related applications.

In this work, Ti/TiO2-RNTs/SnO2-Sb-Ni-La electrodes were developed in three deposition stages. TiO2-RNTs improved the bonding of bottom layer, and Ni-La codoping resulted higher film stability. Compared with other electrodes, electrode exhibits excellent performance a denser structure, OEP (2.17 V), lower Rct (5.36 Ω), longer strengthening life, larger active specific surface area. The degradation oily wastewater revealed an oil removal rate equal to 97.88% under optimal conditions. comparison Ti/TiO2-RNTs/SnO2-Sb obtained via one-step hydrothermal technique, service life by 8.60 times, (RD) current (k = 0.0254 min-1) was enhanced 2.67 whereas remained stable after 10 cycles. Under continuous attack free radicals such as •OH, 48 types organic matter wash decomposed, most alkanes polycyclic aromatic hydrocarbons mineralized. direct current, pulse electrolysis oil-washing can save 47.95% electrical energy, energy consumption chemical oxygen demand per unit mass be reduced 72.02%. Therefore, electrochemical oxidation method is expected reduce loss improve treatment wastewater.

In Situ Growth of Thin‐Layer Nanosheet Arrays of Cu‐Doping NiO for Enhanced Adsorption and Electrooxidation of Biomass

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: May 23, 2025

Abstract With the accelerating depletion of fossil fuels, biomass energy has garnered significant attention as a promising renewable source. The electrocatalytic conversion into high‐value‐added products holds substantial research significance. In this study, catalyst structure is systematically optimized by fine‐tuning ratio adjacent transition metals, nickel (Ni) and copper (Cu), leading to design an ultrathin‐layered nanosheet array catalyst, Cu 1/8 ‐NiO@NF. This exhibits exceptional performance in oxidation 5‐hydroxymethylfurfural (HMF) 2,5‐furandicarboxylic acid (FDCA). shows excellent stability over 40 HMF reaction (HMFOR) cycles at relatively low electrolysis potential 1.45 V (vs RHE). single cycle, achieves complete with 99.5% FDCA yield, 99.6% Faraday efficiency (FE), nearly conversion. A series electrochemical tests reveals that incorporation not only accelerates formation NiOOH reactive intermediates but also enhances charge transfer process. Density Functional Theory (DFT) calculations indicate local substitution improved adsorption lowered barrier. study provides facile approach for developing efficient electrocatalysts oxidation.
