Special Issue Information

Dear Colleague,

Over the past few centuries, the heavy use of fossil fuels has brought large amounts of CO2 emissions, which cause severe environmental issues, such as global warming and climate change. The Intergovernmental Panel on Climate Change (IPCC) has pointed out that the world would have to achieve carbon neutrality by early mid-century to limit global warming to 1.5 °C above pre-industrial levels. This being the case, it is vital to find deep decarbonization methods. The scientific community has proposed two feasible options, namely carbon capture and storage (CCS) as well as carbon capture and utilization (CCU). Additionally, the most promising routes for CO2 mitigation are those that use catalysts and chemical processes for valorization. By applying specific catalysts and suitable operating conditions, CO2 molecules react with other components to form longer chains (i.e., hydrocarbons). Accordingly, efforts should be made to catalytically valorize CO2 (alone or being co-fed with syngas) as an alternative way to reduce greenhouse gas emissions and obtain high-value fuels and chemicals.

The topics of interest for this Special Issue may include but are not limited to, catalyst design and catalytic processes for CO2 conversion, such as thermocatalytic, electrocatalytic, and photocatalytic processes. The submission of original articles, systematic reviews, short communications, and other types of articles on related topics is welcome. All manuscripts will follow standard journal peer review practices, and those accepted for publication will appear in the “Efficient Catalytic CO2 Chemical Fixation” Special Issue. We look forward to receiving your contributions to the Special Issue.

The extensive utilization of fossil fuels has led to a rapid increase in atmospheric CO2 concentration, resulting in various environmental issues. To reduce reliance on fossil fuels and mitigate CO2 emissions, it is important to explore alternative methods of utilizing CO2 and H2 as raw materials to obtain high-value-added chemicals or fuels. One such method is CO2 methanation, which converts CO2 and H2 into methane (CH4), a valuable fuel and raw material for other chemicals. However, CO2 methanation faces challenges in terms of kinetics and thermodynamics. The reaction rate, CO2 conversion, and CH4 yield need to be improved to make the process more efficient. To overcome these challenges, the development of suitable catalysts is essential. Non-noble metal catalysts have gained significant attention due to their high catalytic activity and relatively low cost. In this paper, the thermodynamics and kinetics of the CO2 methanation reaction are discussed. The focus is primarily on reviewing Ni-based, Co-based, and other commonly used catalysts such as Fe-based. The effects of catalyst supports, preparation methods, and promoters on the catalytic performance of the methanation reaction are highlighted. Additionally, the paper summarizes the impact of reaction conditions such as temperature, pressure, space velocity, and H2/CO2 ratio on the catalyst performance. The mechanism of CO2 methanation is also summarized to provide a comprehensive understanding of the process. The objective of this paper is to deepen the understanding of non-noble metal catalysts in CO2 methanation reactions and provide insights for improving catalyst performance. By addressing the limitations of CO2 methanation and exploring the factors influencing catalyst effectiveness, researchers can develop more efficient and cost-effective catalysts for this reaction.
