Metrics details. As climate change becomes increasingly evident, reducing greenhouse gases including CO 2 has received growing attention. Because CO 2 is thermodynamically very stable, its conversion into value-added chemicals such as CO, CH 4 , or C 2 H 4 is difficult, and developing efficient catalysts for CO 2 conversion is important work.

The synthesis of carbon nanotubes CNTs from CO 2 is an attractive strategy to reduce CO 2 emission, but involves extreme reaction conditions and has low scalability. Their intrinsic properties give rise to an enhanced capacitive performance.

Reviewed: June 12th Published: August 16th Carbon dioxide CO 2 is a stable and relatively inert triatomic molecule that exists as a gas at ambient temperature and pressure. Carbon dioxide is generated naturally from various sources such as forest fires, volcanic eruptions, and respiration of living organisms. This steady increase in CO 2 emissions stems from the large consumption of fossil fuels and anthropogenic activity power plants, oil refineries, cement, iron, and steel industries, biogas sweetening, and chemical industry and processing in addition to the wide deforestation for land usage [ 2 ]. Pollution is regarded as the issue of our era, since dominant industries deem its control as an expense that overwhelms the domains that are beneficial to the advances of science. Finding alternatives to indispensable fields such as providing energy, food, drugs, and dyes for medicinal probes, among others, seems to conflict the innovative progress reported every day in academia and industry. The greenhouse effect is one of the utmost contemporary issues in this regard.

The alloy electrode surfaces provided good selectivity and efficiency in electrochemical CO 2 conversion because they provided appropriate binding energies between the metal and the reactive species obtained through CO 2 reduction. Therefore, product selectivity can be modulated by altering the Cu-Sn crystal structure of the electrode. During electrochemical CO 2 reduction, all the prepared Cu-Sn alloy electrodes showed prominent suppression of hydrogen evolution. Surface characterization results showed that the crystal structure of Cu 87 Sn 13 comprised solid solutions that play an important role in increasing the selectivity for CO formation. Greenhouse gases have recently garnered great attention from the viewpoint of global warming and climate change. Since CO 2 gas is a greenhouse gas, CO 2 reduction is required to address the global issue of increasing CO 2 emission [ 1 ].

The role of oxygen vacancies in carbon dioxide electroreduction remains somewhat unclear.

Electrocatalytic reduction of CO 2 to manufacture fuels and other useful chemicals is one of the appealing methods to reuse CO 2. Methanol is the preferred product, with an overpotential of 0. Formaldehyde formed on the surface will be converted into methanol.

Au—Cu bimetallic thin films with controlled composition were fabricated by magnetron sputtering co-deposition, and their performance for the electrocatalytic reduction of CO 2 was investigated. The uniform planar morphology served as a platform to evaluate the electronic effect isolated from morphological effects while minimizing geometric contributions.

A metal-free electrocatalyst for carbon dioxide reduction to multi-carbon hydrocarbons and oxygenates. Odeh5, Robert Vajtai1, Aaron Z. Electroreduction of carbon dioxide into higher-energy liquid fuels and chemicals is a promising but challenging renewable energy conversion technology. Among the electrocatalysts screened so far for carbon dioxide reduction, which includes metals, alloys, organometallics, layered materials and carbon nanostructures, only copper exhibits selectivity towards formation of hydrocarbons and multi-carbon oxygenates at fairly high efficiencies, whereas most others favour production of carbon monoxide or formate.

This paper describes electrochemical reduction of CO 2 directed toward carbon—carbon bond formation via metal—CO 2 adducts. Thus, the difficulty of multi-electron reduction of CO 2 in protic solutions is ascribed to the thermal lability and strong hydride donor character of Ru—CHO.

Electrocatalytic reduction of CO 2 to fuels and chemicals is one of the most attractive routes for CO 2 utilization. Current catalysts suffer from low faradaic efficiency of a CO 2 -reduction product at high current density or reaction rate. Our studies suggest that sulfur accelerates CO 2 reduction by a unique mechanism.

Electroreduction of CO 2 on Cu surface provides the potential in producing hydrocarbons and other multi-carbon products.

DFT calculations reveal that the preference for a H — abstraction by an intrinsically anionic formate moiety is specifically dependent on the electrophilicity of the 2 e — reduced carbon center, which in particular is controlled by the electron-withdrawing capability of the associated substituents on the oxygen.
