“…If not otherwise specified, the catalyst samples were subsequently calcined in static air at 500 °C to convert copper nitrate to oxidic form. Mg 1) is given in our previous work (Soták et al, 2021). To prepare sepiolite-based catalysts, commercial sepiolite (Sigma) was impregnated with metal nitrate solutions following the above-mentioned procedure.…”

Utilization of a low-cost biomaterial, such as bioethanol, to produce value–added compounds for current industry has been investigated. This work is focused on the catalytic transformation of bioethanol into industrially significant alkenes. Catalytic transformation of ethanol was studied using catalysts based mainly on nanostructured materials as Mg-Al hydrotalcites, sepiolites and zeolites doped with Cu, K, Sr, Zn and Mn. The catalytic tests were carried out in a plug-flow reactor in the temperature range of 350—550 °C. Undoped zeolites promote acid-catalyzed dehydration of ethanol, while in case of basic catalysts, such as hydrotalcites, the product distribution is shifted toward butadiene. The impact of the hydrotalcites preparation method on their structure and catalytic activity is reported. It was found that hydrotalcite with well-developed layered structure, prepared by slow hydrolysis, promotes the formation of butadiene (with butadiene yield of 28.2 % at 400 °C vs. ethylene yield of 17.2 % at 550 °C).

“…Cyclopentyl Methyl Ether (CPME) is an asymmetric ether usable as a solvent in organic syntheses [1] with several advantages over other ether-based solvents such as practical immiscibility with water and good chemical stability [2]. It can be classified as an environmentally friendly solvent due to its easy regeneration from reaction mixtures and the possibility of synthesizing it from renewable feedstock [3]. Two synthesis pathways are used nowadays for CPME production: the Williamson synthesis utilizing cyclopentanol and methyliodine [4] and the other one, based on methanol (MeOH) addition on cyclopentene in the presence of an acidic catalyst [2].…”

“…An alternative CPME production route was explored in our previous research [3,5], using zeolites for catalysis in the gas phase. Experimental investigation yielded an estimation of optimal reaction parameters: reaction temperature of 100 • C and feedstock flowrate of 0.1 g/h related to 1 g of catalyst.…”

“…Experimental investigation yielded an estimation of optimal reaction parameters: reaction temperature of 100 • C and feedstock flowrate of 0.1 g/h related to 1 g of catalyst. The resulting cyclopentanol (CYPol) conversion exceeded 80% and the selectivity towards CPME was as high as 82.5% [3]. Cyclopentene (CYPen) and dimethylether (DME) are among the important by-products, with CYPen being hydratable back to CYPol and DME having its use as green coolant as an automotive fuel component [6,7].…”

Organic solar cells (OSCs) have emerged as promising candidates for renewable energy harvesting due to their lightweight, flexible, and low‐cost fabrication potential. The efficiency of OSCs is largely determined by the choice of solvents, which significantly affect the film morphology of the active layers, the intermixed donor‐acceptor domains, and overall device performance. Beginning with an introduction to the importance of solvent selection, the screening and classification of solvents, emphasizing their characteristics and classification based on sustainability, solubility, and other additional considerations are explored. Various non‐halogenated solvents, highlighting commonly used aromatic solvents, biomass‐derived solvents, and water/alcohol‐based solvents are explored. The state‐of‐the‐art donor and acceptor materials, focusing on efficient donor materials such as PM6 and D18, and high‐performing Y‐series acceptors are also presented. Strategies for developing high‐performance OSCs processed using non‐halogenated solvents are examined, including solvent engineering with additive and additive‐free approaches, ternary strategies, and layer‐by‐layer techniques. The fabrication of large‐area devices using non‐halogenated solvents is addressed, focusing on blade‐coating, slot‐coating, and other processing techniques. Finally, this review outlines future research directions in the non‐halogenated solvent processing of OSCs, emphasizing the need for continuous innovation to overcome existing limitations and propel OSC technology toward commercial viability.
