Levulinic acid (LA) is an important biomass-derived compound, that can be easily obtained by acid hydrolysis from biomass. LA can be transformed into high valuable chemical compounds by catalytic route, as for example in γ-valerolactone (GVL), which has important applications as additive or precursor of biofuels. The transformation of LA to GVL requires a hydrogen source and a proper catalyst. In this work, monometallic catalysts based on Ru and Ni as well as bimetallic RuNi supported on a zeolite have been synthesized and characterized by XRD, XPS and TEM. The hydrogenation of LA into GVL has been studied with these Ni/Ru catalysts using non-conventional hydrogen sources and the results have been compared with the traditional hydrogen source (pressurized molecular hydrogen). The alternative hydrogen sources used are: i) a system based on metallic Zn and water, where Zn can decompose water into hydrogen but it is oxidized to ZnO, ii) a combined system that uses hydrogen produced by photoelectrochemical (PEC) water splitting (WS) using a nanostructure of TiO₂. The bimetallic catalyst led to the highest yield to GVL when Zn was used in the reaction, but the yields achieved are not remarkable (less than 25 %). Conversely, the monometallic catalyst based on Ru was the one that exhibited the highest yield to GVL when pressurized and PEC hydrogen were used. In this case, yields to GVL exceeding 95 % were achieved at 30 °C although the reaction time required was lower when pressurized hydrogen was used. Interestingly, a new system for PEC WS has been proposed, improving the contact between hydrogen and levulinic acid. This new system decreases the induction time, and enhances the GVL formation, especially at low reaction times. Finally, these catalysts are stable after reaction regardless of the source of hydrogen employed.</div></div>","PeriodicalId":264,"journal":{"name":"Catalysis Today","volume":"455 ","pages":"Article 115311"},"PeriodicalIF":5.2,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143785548","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}

To understand this behavior, the reaction mechanism was investigated using in situ FTIR spectroscopy, which revealed two distinct pathways. At low temperatures, an Eley-Rideal mechanism dominates, where ammonia adsorbed on Lewis acid sites reacts with gas-phase NO, forming nitrosamine intermediates that rapidly decompose into N₂ and H₂O. At high temperatures, the Langmuir-Hinshelwood mechanism becomes predominant, involving the adsorption of both NH₃ and NO, with NO undergoing oxidation to nitrate species before reacting with NH₃-derived intermediates. The excessive deprotonation of adsorbed NH₃ under these conditions leads to the formation of N₂O as a by-product.

This study presents a BPA removal system utilizing a packed bed reactor (PBR) with supported enzymatic catalyst. In previous research, we demonstrated that the laccase@NH₂-MIL-53(Al) catalyst was highly effective in degrading BPA in a batch reactor, thanks to its high enzyme loading and minimal enzyme leaching.

In this work, we extend the application of this catalyst to continuous flow conditions in a PBR, achieving superior removal efficiencies compared to batch processes. Under continuous flow, the biocatalyst maintained over 90 % BPA removal for extended periods, even at higher contaminant concentrations than typical in environment. The system exhibited remarkable stability with no diffusional limitations, suggesting high substrate accessibility to the enzyme. Additionally, chemical oxygen demand (COD) analyses of treated samples showed minimal increases, reinforcing the environmental compatibility and efficiency of the system.

Physicochemical characterization revealed that Co doping induces synergistic effects, including Ni-Co alloy formation that mitigates sintering, a decrease in metal particle size from 25.7 nm to 17.1 nm, increased basicity from 120 to 183 μmol·g_cat⁻¹, and enhanced reducibility from 90 % to 98 %.

A promising approach is the use of highly abundant and economic lignocellulosic waste biomass, from which furanic compounds can be derived. However, to obtain C₉-C₁₅ jet fuel-compatible products, C-C coupling strategies are mandatory to increase the chain length of the furanic platforms. Furthermore, there exists an uncovered potential for integrating fermentation-derived platforms, like acetoin, in advanced bio-jet fuel production routes. In this sense, this work explores the C-C coupling of acetoin, a fermentation-derived molecule, with 2-methylfuran (2-MF), a lignocellulose-derived molecule that can be obtained from selective hydrogenolysis of furfural, via hydroxyalkylation/alkylation (HAA). This solvent-free acid-catalyzed reaction yields oxygenated adducts incorporating one molecule of acetoin and 1-3 molecules of 2-MF (9–19 C atoms) that display high potential as bio-jet fuel precursors. However, side reactions are also present, coming from the auto-condensation of acetoin and/or 2-MF, yielding heavier or more oxygenated undesired compounds, so that selectivity appears as the key parameter in the catalyst performance. In this work, sulfonic acid-based resin Amberlyst-15 has displayed high activity and selectivity towards the most interesting di-condensed C₁₄ compound, herein denoted as Ac(MF)₂, which evidences the benefits of applying strong Brønsted acid sites allocated within a polymer matrix in high surface concentration.

Amberlyst-15 catalyst was tested in a 5-cycle reusability experiment, keeping an acceptable level of catalytic activity and selectivity despite evidence of fouling due to the formation of organic deposits.
