Recently, the team led by Dr. Dehui Deng, a researcher at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, was invited to publish a comprehensive review article on the selective regulation of carbon monoxide in CO2 hydrogenation. The review systematically outlines the research progress in CO2 hydrogenation to carbon monoxide and discusses prospective strategies for selective regulation, existing challenges, and future directions in the field. The findings have been published in the journal "Chem".
Utilizing renewable energy-based green hydrogen to react with CO2 for the production of high-value chemicals or fuels is considered an effective strategy for carbon reduction and CO2 resource utilization. Achieving high selectivity in CO2 hydrogenation is crucial for reducing separation and recycling costs and enhancing production efficiency. However, challenges remain in selectively regulating CO2 hydrogenation due to the complex reaction network and the coexistence of various active sites on catalyst surfaces.
Previously, the team collaborated to develop a sulfur vacancy-rich two-dimensional molybdenum sulfide catalyst, enabling low-temperature, efficient, and long-term CO2 hydrogenation to methanol. Compared to traditional catalyst systems, this catalyst can achieve efficient CO2 conversion at low temperatures, even at room temperature, advancing the scale-up of "low-temperature CO2 conversion" technology.
Building on their earlier work, the team was invited to write a review on the selective regulation of CO in CO2 hydrogenation, focusing on the synthesis of carbon monoxide products. The review systematically outlines the development of various catalyst systems, emphasizing the regulation principles of CO2 hydrogenation selectivity such as active metal components, metal dispersion, carriers, and additives. It also discusses key challenges in the field and prospects for future research directions and opportunities.
