Urea formation from carbon dioxide and ammonia at atmospheric pressure

A novel method of production of ethanol by carbon dioxide with steam

“…Such negative corona discharge may create anionic gases, which could capture free electrons to form strong reducing agents for CO 2 conversion, differently from conventional low-temperature plasma technology which just create oxidizing-reducing at the same time. We have found that by using negative corona, useful products, e.g., urea [11] and tetraiodomethane [12] could be produced.…”

Synthesis of Alkaline‐Soluble Cellulose Methyl Carbamate Using a Reactive Deep Eutectic Solvent

“…Urea and many of its derivatives are promising chemicals for cellulose modification because they can be produced in a sustainable way from CO 2 , thus providing a method by which to attach CO 2 to biomaterials with improved properties. In this study, the synthesis of novel cellulose methyl carbamate (CMeC) was studied using a reactive deep eutectic solvent (DES) based on dimethylurea and ZnCl 2 .…”

“…[17] Cellulose carbamate has good solubility in NaOH solution, especially in the presence of ZnO, and it has been used to produce cellulose-based membranes [18] and filaments. [19] Urea and many of its derivatives are promising chemicals for cellulosem odification because they can be produced in as ustainable way from CO 2 , [20,21] thus providing am ethod by which to attach CO 2 to biomaterials with improved properties. In this study,t he synthesis of novel cellulose methyl carbamate (CMeC) was studied using ar eactive deep eutectic solvent (DES) based on dimethylurea and ZnCl 2 .D ESs show promising properties, such as good solvent capacity,a nd in chemical reactions,t hey can function as both catalysts and reagents.…”

Electrocatalytic Conversion of Carbon Dioxide and Nitrate Ions to Urea by a Titania–Nafion Composite Electrode

“…[3] The chemical conversion of CO 2 to valuablep roducts such as hydrocarbons, syngas, formate, and other chemical commodities is crucial to mitigate the greenhouse effect causedb y CO 2 in the atmosphere. The composite electrode was constructed by dropcasting the mixtureo fP 25 titania and Nafion solution on an indium-doped tin oxide (ITO) electrode.…”

“…[3] The chemical conversion of CO 2 to valuablep roducts such as hydrocarbons, syngas, formate, and other chemical commodities is crucial to mitigate the greenhouse effect causedb y CO 2 in the atmosphere. [1] Shibata et al demonstrated the possibility of urea synthesis by electrochemical conversion of CO 2 and nitrate/nitrite ions by gas diffusion electrodes modified with variety of electroactive materials at ambient room temperature and atmospheric pressure.…”
