“…Catalysts were synthesized containing the oxides of molybdenum, vanadium, tungsten, and copper with compositions B1-type and B2-type based on the methodologies adapted from patents available in the public domain [10]. These compositions were synthesized by using different preparation methods, namely, evaporation (EV), evaporation followed by hydrothermal treatment (EV+TH), and hydrothermal treatment (TH).…”

Mixed oxides of Mo‐V‐W‐Cu were prepared by three different synthesis methods, namely, evaporation (EV), hydrothermal treatment (TH), and evaporation, followed by hydrothermal treatment (EV‐TH). The catalyst samples were characterized by X‐ray diffraction (XRD) and fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), and N2 adsorption/desorption techniques. Subsequently, their catalytic performance was evaluated for the oxidation of acrolein to obtain acrylic acid. The results revealed that the composition of the crystalline phases of the mixed oxide catalysts influences their catalytic performance, and this effect varies depending on the synthesis method. The catalysts synthesized by EV‐TH showed better catalytic results than catalysts synthesized solely via EV or TH methods. This improvement may be attributed to the higher content of vanadium oxides found in the samples of EV‐TH, along with the formation of V0.35Mo4.65O14 as the predominant crystalline phase.

“…Utilizing CO 2 as a feedstock for chemical production is a major goal for the creation of a circular economy that minimizes non-renewable inputs . C–H carboxylation, the conversion of a C–H bond into a carboxylate (C–CO 2 – ) with CO 2 and a base (Scheme ), has attracted interest as a way to utilize CO 2 for the preparation of carboxylic acids and their derivatives, which comprise a large number of fine and commodity chemicals. − C–H carboxylation is conceptually appealing because it takes advantage of the oxidation state of CO 2 and avoids the limitations of other methods to synthesize carboxylic acid derivatives, such as the need to pre-install heteroatom functionality or perform harsh oxidations. − However, most C–H carboxylation methods require (super)-stoichiometric amounts of highly reactive, resource-intensive reagents to activate the C–H bond, which negates the carbon benefit of using CO 2 as a feedstock, generates large amounts of waste products, and incurs prohibitive costs for anything other than specialty chemicals. To impact sustainability, it is critical to develop alternative carboxylation methods that utilize simple reagents that can be easily regenerated.…”

Improving Carbonate-Promoted C–H Carboxylation Using Mesoporous Carbon Supports

C–H carboxylation is an attractive way to utilize CO2 for chemical production provided that it does not consume resource-intensive reagents. Alkali carbonates dispersed into the pores of mesoporous supports display strongly basic reactivity under CO2, allowing them to be used as base promoters for C–H carboxylation of (hetero)arenes in the absence of other reagents or catalysts. Mesoporous oxides are convenient support materials, but only a relatively small fraction of the dispersed carbonate (ca. 10–20%) is converted to carboxylate products when metal oxide supports are used. Here, we compare mesoporous oxide and carbon supports and investigate the dependence of carbonate reactivity on the pore structure. We show that using mesoporous carbon supports can increase the carbonate conversion by 2–4× when compared to oxide supports. This improved carbonate reactivity is maintained across a variety of mesoporous carbons with different pore structures (ordered vs disordered) and pore diameters, indicating that the dispersed carbonate is intrinsically more reactive on the surface of a carbon material compared to an oxide surface. Reaction of the carboxylate products with dimethyl carbonate yields isolable methyl esters as the final product and regenerates the dispersed carbonate. We show that mesoporous carbon supports are robust to at least five cycles of successive C–H carboxylation and methylation. Understanding how the support structure affects dispersed carbonate reactivity is valuable for advancing C–H carboxylation toward practical application and utilizing these materials in other CO2 transformations.
