我科学家提出自然光驱动二氧化碳转化通用方案

Core Insights - The research team from the Chinese Academy of Sciences has developed a universal strategy to overcome the challenge of synchronously utilizing photogenerated electrons and holes in artificial photosynthesis, which is crucial for the conversion of carbon dioxide resources [1][3] Group 1: Research Breakthrough - The team mimicked the physiological mechanism of plants that temporarily store photogenerated electrons, designing a silver-modified tungsten trioxide material with electron storage capabilities [3] - This innovative material allows for precise control over the electron release process, enabling efficient cooperative conversion of carbon dioxide and water under natural light [3] Group 2: Efficiency and Scalability - Experimental results indicate that when combined with the catalytic active component cobalt phthalocyanine, the carbon dioxide conversion efficiency of the new material is nearly 100 times higher than that of pure catalysts [4] - The proposed strategy demonstrates good universality and scalability, making it adaptable to various composite catalyst systems, thus providing a feasible technological pathway for large-scale solar energy conversion of carbon dioxide into clean energy [4]
