These pathways are essential for transforming renewable biomass into valuable chemicals, thereby facilitating the shift towards a circular economy and diminishing our dependence on fossil fuel-derived resources. Herein, three MnO₂ catalysts with different crystal structures were prepared for the efficient catalytic oxidation of HMF to FDCA. The results showed that α-MnO₂ exhibited higher oxidizing activity per unit specific surface area and an appreciably large specific surface area, however, its overall catalytic activity was found to be less than that of β-MnO₂. XRD, SEM, and other characterizations suggest that the presence of smaller nanorods or amorphous particles with reduced crystallinity on the surface of the α-MnO₂ catalysts could be responsible for a decreased lattice oxygen content, thereby diminishing their catalytic activity. To validate this conjecture, this paper cites for the first time the application of a dilute nitric acid immersion treatment in the chemical industry to eliminate amorphous structures from catalysts. The α-MnO₂-H⁺ catalyst, prepared using this innovative method demonstrated exceptional activity in facilitating the conversion of HMF to FDCA under more stringent reaction conditions than any monometallic catalysts previously reported. According to the kinetic analysis of the reaction, it was established that the oxidation of 5-formyl-2-furancarboxylic acid (FFCA) to FDCA constitutes the rate-limiting step within the entire oxidation process. On this basis, FT-IR studies showed that the oxidation initiates at the -CHO terminus of HMF, leading to the formation of intermediates 5-hydroxymethylfurfurylacetic acid and 5-formylfurfurylacetic acid within the Mn⁴⁺/Mn³⁺ redox cycle. In conclusion, the enhancement of catalytic activity by diluting nitric acid immersion treatment presents a promising avenue for further research and application in the field of green chemistry.</div></div>","PeriodicalId":393,"journal":{"name":"Molecular Catalysis","volume":"578 ","pages":"Article 114995"},"PeriodicalIF":3.9,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of benzenesulfonic acid (PhSO₃H) can enhance the conversion of toluene to 70.1 % and significantly improve the BC selectivity, which likely originates from the particle aggregation and proton-coupled electron transfer (PCET) effect caused by the π-π interaction between AQ-COOH, PhSO₃H and aromatic substrates. The PCET mechanism was successfully established by introducing PhSO₃H into the AQ-COOH-based photooxidation system, resulting in efficient photooxidation of diverse aromatic substrates.

This research introduces and enhances a non-noble metal catalyst, Cs-V, by doping with the rare-earth element La for the CDPF. The impact of La doping on the Cs-V-based soot oxidation catalyst was quantitatively studied using physical and chemical analysis, activity testing, and density functional theory (DFT) techniques. Findings indicated that introducing La into the Cs-V-based non-noble metal catalyst led to an increase in both the surface area and pore volume by 41 % and 18.4 %, respectively. The addition of La enhanced both the clustering and spatial distribution of catalyst particles, positively impacting absorption and catalytic activity. Doping with La significantly increased the chances of oxygen adsorption and dissociation activation in catalytic processes, enhancing the chance of soot-oxidation, lowering the activation energy to 62.1 kJ/mol, and decreasing T₁₀(the temperature at which the conversion rate of soot begins to reach 10 %), T₉₀(the temperature at which the conversion rate of soot reaches 90 %), and, T_m(the peak temperature at which the conversion rate of soot reaches) by 70.2 °C, 66.9 °C, and 69.1 °C respectively in contrast to their un-doped counterparts, while concurrently, La doping led to an average 4.5 % boost in the CDPF regeneration effectiveness.
