“…Owing to their unique structural properties (acidity, polarity, and surface properties), carboxylic acids have been widely applied for the syntheses of pharmaceuticals, agrochemicals, coatings, cosmetic ingredients, disinfecting products, and other chemicals. , Among the carboxylic acids, adipic acid (AA) is of particular interest with a tremendous demand all over the world. It is a key monomer for the synthesis of important polymers such as nylon-66, − plasticizers, lubricants, and food additives. The traditional industrial process for producing AA involves the hydrogenation of petroleum-derived benzene.…”

Selective oxidative cleavage of C(OH)−C or C(O)−C bonds in cyclohexanol and cyclohexanone (KA oil) to produce adipic acid (AA), a monomer for the synthesis of nylon-66, is of significant importance for the petrochemical industry. Herein, we report an electrochemical method to improve the efficiency for upgrading KA oil into AA. Free-standing electrodes consisting of hydroxides (Ni(OH) 2 and Mn-doped Ni(OH) 2 ) supported by carbon paper were fabricated via an in situ electrodeposition process and further examined for KA oil conversion. The morphology and structures of the samples were characterized by field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Raman spectroscopy. The electrochemical performance of the samples was studied by cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance spectroscopy. The products of KA oil oxidation were analyzed by high-performance liquid chromatography. The introduction of manganese into nickel hydroxides enhanced the catalytic performance in terms of activity and product selectivity. Specifically, the optimal sample exhibited a current density of 50 mA mg −1 and selectivity of 46.8%, which are superior to those of pure nickel hydroxides. Such enhancement was attributed to the electronic interaction of manganese with nickel hydroxides, thereby modifying the adsorption of the substrates. Interestingly, the introduction of Mn into nickel hydroxides had negligible effects in the oxygen evolution reaction. The effects of critical parameters including substrate composition, reaction temperatures, KOH concentrations, and electrolysis time on the conversion of KA oil were investigated.

Limited research has been dedicated to exploring the potential reuse and creation of value‐added products from corn stover. Existing gaps in current research underscore the need for waste biorefineries that adhere to the principles of a circular bioeconomy to maximize the value of corn stover. This review uses bibliometric analysis from the past decade to examine the potential and pathways for converting corn stover into energy and value‐added products within the biorefinery framework. The data were processed using the Web of Science® database and analyzed with the VosViewer® bibliometric software's, Bibliometrix package in R and Gephi, generating keyword‐based maps. A total of 2557 experimental articles and 30 reviews on corn stover research were analyzed. The bibliometric study revealed that the primary research focuses on pretreatment technologies for converting corn stover into value‐added products, bioenergy and biofuels. The main technologies employed include acid, alkaline and enzymatic hydrolysis, as well as torrefaction anaerobic digestion and steam explosion. The pretreatment processes yield sugars, xylooligosaccharides and organic acids. Additionally, the studies explored the use of corn stover biochar for soil remediation and adsorption processes. This review aims to enhance the understanding of technological pathways explored in previous research, contributing to the evaluation of sustainable processes for utilizing corn stover byproducts. Ultimately, it promotes environmentally conscious agroindustry practices that align with circular economy principles and sustainable development.
