The most important methods for the electrochemical reduction of carbon dioxide on flat metallic cathodes have been systematically summarized using a novel classification approach.

Meseha, Mina Anis Amin Ibrahim Solar-driven electrocatalytic formation of hydrogen and syngas for downstream catalytic hydrogenation and hydroformylation reactions. PhD thesis, University of York. Metal and metal phosphide electrocatalysts were investigated for the electrochemical reduction of CO2 and water into CO and hydrogen, respectively. Both electrocatalysts were able to produce H2 at a sufficient rate to support hydrogenation at room temperature and pressure. Copper and copper phosphide electrocatalysts were used for the CO2 reduction reaction.

Electrochemical and Electrocatalytic Reactions of Carbon Dioxide

Conversion of light and electricity to chemicals is an important component of a sustainable energy system. The exponential growth in renewable energy generation implies that there will be strong market pull for chemical energy storage technology in the near future, and here carbon dioxide utilization must play a central role. The electrochemical conversion of carbon dioxide is key in achieving these goals. Carbon Dioxide Electrochemistry showcases different advances in the field, and bridges the two worlds of homogeneous and heterogeneous catalysis that are often perceived as in competition in research. Chapters cover homogeneous and heterogeneous electrochemical reduction of CO2, nanostructures for CO2 reduction, hybrid systems for CO2 conversion, electrochemical reactors, theoretical approaches to catalytic reduction of CO2, and photoelectrodes for electrochemical conversion.

The recycling of atmospheric molecules for use as fuels and chemicals is a goal which can only be achieved through a deeper understanding of catalytic processes, particularly electrocatalysis whereby redox transformations can be interfaced with solar or nuclear energy input. Carbon dioxide is a prototypical small molecule in many regards since it is chemically inert. In addition, because of the likely role of carbon dioxide in global temperature cycles, it will be imperative in the future to regulate the output from industrial processes. The purpose of this book is to present a unified discussion of the carbon dioxide chemistry which is necessary for the understanding and design of electrochemically-driven processes for the reduction of carbon dioxide and to provide an impetus for the further development of electrocatalytic carbon dioxide chemistry.

The electrochemical reduction of carbon dioxide is the conversion of carbon dioxide to more reduced chemical species using electrical energy. It is one possible step in the broad scheme of carbon capture and utilization. The first examples of electrochemical reduction of carbon dioxide are from the 19th century, when carbon dioxide was reduced to carbon monoxide using a zinc cathode. Research in this field intensified in the s following the oil embargoes of the s. Propanol and 1-butanol have also been produced via CO 2 electrochemical reduction, albeit in small quantities. In carbon fixation , plants convert carbon dioxide into sugars, from which many biosynthetic pathways originate. The catalyst responsible for this conversion, RuBisCo , is the most common protein on earth.

Electrochemical reduction of carbon dioxide

This paper presents the experimental investigation of copper loaded carbon nanotubes CNTs electrocatalysts for the electrochemical reduction of carbon dioxide. The electrocatalysts were synthesized by homogeneous deposition precipitation method HDP using urea as precipitating agent. Linear sweep voltammetry LSV and chronoamperometry CA were used to investigate the activity of the as-prepared catalysts for the electrochemical reduction of carbon dioxide. Gas chromatograph with TCD was used to analyze liquid phase composition. The faradaic efficiency for methanol formation was estimated to be

Anthropogenic CO 2 emissions engender a severe threat to the global ecosystem and consequently are a growing concern associated with traditional means of energy production. Direct electrocatalytic reduction of CO 2 into energy-rich fuels and value-added chemical feedstocks provides a promising route to realize a carbon-neutral energy cycle, and at the same time, store the electricity generated from intermittent renewable-energy sources. Kinetically, multi-proton-coupled electron transfer steps upon CO 2 RR render sluggish reaction processes [ 1 ].

Novel Trends in Electroorganic Synthesis pp Cite as. After addition of EtI, unsubstituted amines and alcohols are converted into the corresponding ethyl carbamates and carbonates in good yields. Owing to these changes, the solutions acquire an interesting carboxylating power versus amines and alcohols. Our method of synthesis of organic carbamates and carbonates relies on this carboxylating power.
