Recently, Research Center for Solar Driven Carbon Neutrality has made a breakthrough in the field of photothermal high-purity gas preparation. Related work "High-Purity Carbon Monoxide Production via Photothermal Formic Acid Decomposition over Fluorite ZrO2"was published in Nature Catalysis with Hebei University as the main research institution (IF=42.8, 2024). Dr. Li Yaguang is the first and corresponding author of the paper, Professor Ye Jinhua and Researcher Luo Yanhong from the Institute of Physics of the Chinese Academy of Sciences are the co-corresponding authors, and student Liu Bang and Dr. Yuan Dachao from Hebei Agricultural University are the co-first authors.
Ultra-high purity carbon monoxide (CO) is a special gas widely needed in high-tech industries such as integrated circuit manufacturing. Traditional high-purity CO preparation relies heavily on advanced gas separation technology, resulting in environmental pollution and high costs, and heavily relies on foreign imports. In order to break through the problem of high-purity CO preparation, Li Yaguang, Ye Jinhua and Luo Yanhong jointly propose a new high-purity CO preparation route of "photothermal catalytic formic acid cracking". It is revealed that fluorite-structured zirconia can efficiently catalyze the cracking of formic acid to produce CO and block the generation of impurity gases through the combination of theory and experiments, which achieves the goal of direct production of high-purity CO. Combined with a photothermal catalytic unit, the system can produce more than 1,538 liters/m2 of high-purity CO per day, which not only demonstrates great potential for industrialization, but also initiates a new era in the production of high-purity gases using green energy. In the future, the research may lead the industrial revolution of high-purity gas preparation and contribute to the independent innovation of energy and science and technology of the country.
