Hydrogen energy is a clean and highly efficient energy source. Although its use has attracted worldwide attention, how to realize large-scale low-energy consumption and efficient and selective hydrogen production from sustainable sources is still a problem to be solved in hydrogen energy utilization. One of the key issues.
Recently, Li Yang's research group of the Institute of Organic Chemistry at the Frontier of Xi'an Jiaotong University and the team of Prof. Matthias Beller from the Institute of Catalysis at Leibniz in Germany have cooperated with each other. After nearly three years of research, the use of non-food biomass, such as straw and corn stover, has been developed. , Rice stalks, reeds, sugarcane bagasse, bamboo swarf, and daily-use garbage, such as cardboard, waste newspapers, as raw materials, through the series of 160 °C to convert the main components of biomass in cellulose and hemicellulose to formic acid oxidation Catalytic 'oxidation catalysis' for the conversion of the major components of biomass in cellulose to formic acid at 90°C and the 'reduction catalytic' for liquid hydrogen release from hydrolytic oxidation of biomass at 90°C without purification, ie 'One-pot two-step process' for hydrogen production with up to 95% yield, associated CO2 (CO 2) Carbonate (CO) and Methane (CH) produced by carbonate conversion 4The content of these products is not more than 22ppm and 2ppm, respectively. It can be directly applied to the conversion of hydrogen fuel cells to electric energy, and hydrogen production can be performed with high efficiency and selectivity under relatively mild conditions. The hydrogen production line can be used for laboratory-scale amplification of 10g.
The results were published in the form of papers in the top journal of the international catalysis field Nature Catalysis. The paper titled 'Streamlined hydrogen production from biomass'. Postdoctoral researcher Zhang Ping and PhD student Guo Yujun are the first authors of this article. The hospital is the first communication unit of the paper.
