“道法自然”的人工光合作用

Artificial photosynthesis learning from nature

近年来,模拟自然界光合作用,开发高太阳能转化效率的人工光合作用体系引起了人们的广泛关注,成为化学前沿研究领域。水氧化或二氧化碳还原都需要较高的活化能,想要实现人工光合作用的大规模工业化,必须降低反应能垒以提升反应速率。在高中化学教学过程中,通过展示催化剂参与的人工光合作用过程,揭示催化剂参与的能源转换过程,引导学生理解人工光合作用的瓶颈,提高学生对化学领域的兴趣,培养科学精神与社会责任的化学核心素养,激发他们探索前沿科学领域并立志解决人类面临的发展问题。

In recent years,it has attracted widespread attention in the field of frontier research to simulate photosynthesis in nature and develop artificial photosynthesis systems with higher solar energy conversion efficiency.CO2 to low-valent carbon compounds,providing fuel and industrial raw materials for humans.Water oxidation and carbon dioxide reduction requires high activation energy.The large-scale industrialization of artificial photosynthesis can only be achieved by reducing the reaction energy barrier and improving the reaction rate.Combination of experiments about artificial photosynthesis with chemistry education in senior high school can help student to understand the importance of catalysis for artificial photosynthesis and the bottleneck of artificial photosynthesis,improving their interest in chemistry and cultivate the chemical accomplishment of scientific spirit and social responsibility,stimulating them to explore cutting-edge field of science and to solve be development problems facing mankind.
