AI Article Synopsis
- There has been a growing interest in using biomass, particularly glucose, as a renewable feedstock in the chemical industry to produce valuable products like carboxylic acids, especially gluconic and formic acids.
- This study focused on the non-catalyzed wet oxidation of glucose with hydrogen peroxide, achieving molar yields of up to 15% for gluconic acid and 64% for formic acid, with glucose conversion rates ranging from 40% to over 80% at high temperatures.
- The research also explored how varying temperatures can influence the distribution of products and the rates of the reactions, as well as the interaction between wet oxidation and electrolytic reactions.
Article Abstract
An increasing interest in biomass as a renewable feedstock for the chemical industry has risen over the last decades, and glucose, the monomer unit of cellulose, has been widely studied as a source material to produce value-added products such as carboxylic acids, mainly gluconic and formic. In this work, the non-catalysed wet oxidation of glucose using hydrogen peroxide has been analysed, obtaining molar yields to gluconic and formic acids up to 15% and 64%, respectively. Glucose conversion was generally between 40 and 50%, reaching over 80% under the highest temperature (200°C). An appropriate choice of temperature can tune product distribution as well as reaction rates. The interaction of the wet oxidation with an electrolytic reaction was also analysed.

Developing ethanol oxidation electrocatalysts with high catalytic activity, durability, and resistance to CO poisoning remains a major challenge. High-entropy alloys (HEAs) with unique physical and chemical properties have garnered substantial attention. Herein, a class of HEA nanodendrites are designed by a simple wet-chemical method.

Whether the catalyst can realize the non-CO pathway is the key to greatly improve the catalytic activity and stability of methanol oxidation reaction (MOR). It is feasible to optimize the reaction path selectivity by modifying organic ligands and constructing single-atom systems. At the same time, heterogeneous metal nanosheets with atomic thickness have been shown to significantly enhance the catalytic activity of materials due to their ultra-high exposure of active sites and synergistic effects.

Coastal lagoons, acting as transitional zones, are increasingly threatened by microplastic (MP) pollution. This study investigates the spatio-seasonal distribution of MPs in Chilika Lagoon sediments to propose effective mitigation measures. MPs were extracted using density flotation and wet peroxide oxidation, followed by quantitative analysis with a stereomicroscope and qualitative analysis with micro-Fourier Transform Infrared (μ-FTIR) spectroscopy.

Chitosan (CS) has excellent film-forming properties; unfortunately, its use as a film wound dressing is limited because of its weak mechanical properties, especially in its wet state. For this reason, modifications with different materials are investigated in this study. The aim of this work was the combination of chitosan with poly (vinyl alcohol) (PVA), magnesium oxide nanoparticles (MgO), and glycerol as a plasticizer agent which can strengthen CS films, increase their flexibility, and enhance their resistance to microbes.

In this paper, the road performance and mechanism of cement-phosphogypsum-red clay (CPRC) under dry and wet cycling were systematically investigated using 5% cement as curing agent, the mass ratio of phosphogypsum: red clay = 1:1, and 5% SCA-2 as water stabilizer. The road performance of dry and wet cycle mix was verified with the National Highway G210 Duyun Yangan to Yingshan Highway Reconstruction and Expansion Project as a test road to provide a scientific basis for the application of cement-phosphogypsum-red clay on roads. The results show that the cement-phosphogypsum-red clay unconfined compressive strength decreases with the increase of the number of wet and dry cycles, with a larger decay in the first three times and leveling off thereafter.
