2 Reduction: A Density Functional Approach
Published in Aneeya Kumar Samantara, Satyajit Ratha, Electrochemical Energy Conversion and Storage Systems for Future Sustainability, 2020
Due to the ease of their availability and cost-effectiveness, carbon-based nanostructures are considered to be the most suitable catalysts for electrochemical reduction of carbon dioxide. In addition, these carbon-based materials have certain advantages over metal surfaces as electrocatalysts for ECR, because of their chemical inertness at negative potential ranges in both aqueous and non-aqueous media and high overpotential values for the competing HER (Siahrostami et al., 2017; Yang, Waldvogel, and Jiang, 2016). Longer life span, efficient, and tunable surface chemistry by making stronger bonds between carbon and different surface modifiers and better electrochemical activity for a variety of compounds makes them potential electrodes for the electrochemical reduction of CO2 (Yang, Swain, and Jiang, 2016).

CO2, one of most notorious greenhouse gases, is one of the main causes of the increase of global average temperature, climate change, ocean acidification, and extreme weather. Since the industrial revolution, accelerated consumption of fossil fuels has resulted in excessive emission and accumulation of CO2 in the atmosphere. In 2017, the global average concentration of carbon dioxide in the environment reached 405 ppm [1–3], and it would be reaching 600 ppm by the end of the century [4–6]. This will cause severe damage to the sustainable development of the earth's ecological environment. So, how to efficiently reduce the content of carbon dioxide in the atmosphere and effectively utilize it has become an important research topic [7–9]. Different approaches have been proposed to address the CO2 issue, such as increasing the efficiency of fossil fuel combustion, enhancing the physical capture and storage of carbon dioxide, and enhancing the conversion of carbon dioxide to valuable chemicals [10,11]. Among these solutions, electrochemical reduction of carbon dioxide is an effective and proven technology. It’s reducing carbon dioxide emissions and providing sustainable energy for society [12–14].
