On August 6, the National Institute of Clean-and-low-carbon Energy (NICE) under CHN Energy made significant progress in the field of CO2 catalytic conversion. The research team successfully developed a self-supporting iron-based bifunctional catalyst with high structural strength and thermal conductivity, achieving highly selective CO2 hydrogenation to olefins. The single-pass yield of olefins has reached the highest level currently reported.

The efficient conversion of CO2 is of strategic importance for addressing energy crisis and achieving carbon neutrality. Coupling renewable green hydrogen with CO2 catalytic conversion can enable the sustainable production of green fuels like green methanol and jet fuel, as well as high-value-added chemicals such as olefins. In their previous work, the NICE team successfully produced an efficient synergistic FexC-FexOy-M catalyst based on an improved precipitation method, enabling the one-step hydrogenation of CO2 to linear α-olefins. They completed kilogram-scale catalyst scale-up verification and long-term stability tests (>1,000 hours) and analyzed the catalyst's active phase structure and dynamic changes using various in-situ characterization techniques.

This research provides a promising technological pathway for the efficient conversion and utilization of CO2, addressing the engineering challenges related to catalyst structural strength and heat transfer in the transition from laboratory experiments to industrialization.
