Hydrogen energy is a clean and highly efficient energy source. Although its use has attracted worldwide attention, how to achieve large-scale low-energy, high-efficiency, and high-selectivity hydrogen production from sustainable sources is still a problem to be solved in hydrogen energy utilization. One of the key issues.
Recently, the Research Group of Li Yang, Researcher of the Institute of Organic Chemistry at the Frontier of Xi'an Jiaotong University, and the team of Prof. Matthias Beller of 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 stalks, has been developed. , rice stalks, reeds, sugarcane bagasse, bamboo shavings, and daily-use waste, such as cardboard, waste newspapers, as raw materials, through the tandem at 160 °C to convert the main components of biomass in cellulose and hemicellulose to formic acid "oxidation "Catalytic oxidation" and "oxidation catalysis" for the conversion of cellulose and hemicellulose, the main components of biomass, into formic acid at 90°C, and "reduction catalysis," at 90°C, for the hydrogen evolution of liquids in the hydrolysis of biomass, without purification, ie "One-pot, two-step process" for hydrogen production with a yield of up to 95%, the associated carbon dioxide (CO2) is converted to carbonate by lye capture, and produces no more than 22 ppm of carbon monoxide (CO) and methane (CH4), respectively With 2 ppm, it can be directly applied to the conversion of hydrogen fuel cells to electric energy, and hydrogen production can be achieved with high efficiency and selectivity under relatively mild conditions. The hydrogen production line can be subjected to a laboratory-scale 10 g scale-up reaction.
The results were published in the form of papers in the top journal of the international catalysis field Nature Catalysis. The paper was titled "Streamlined hydrogen production from biomass". Postdoctoral Zhang Ping and PhD student Guo Yujun of the Frontier Academy are the first authors of this article. The Frontier Institute is the first communication unit of the thesis.
