嫦娥六号月球样品中首次发现天然单壁碳纳米管与石墨碳，为研究月球演化史提供关键数据

Core Insights - The research team from Jilin University has made a significant discovery by identifying naturally formed single-walled carbon nanotubes and graphite carbon in lunar soil samples from the Chang'e 6 mission, marking the first such confirmation internationally [1][3] - This finding reveals the intricate nature of "high-energy physical-chemical processes" on the lunar surface and indicates more active geological activity on the far side of the moon, providing crucial data for understanding lunar evolution [1] Group 1 - The study utilized various microscopic and spectroscopic techniques to systematically characterize the lunar samples collected from the far side of the moon, leading to the first clear identification of graphite carbon and the natural formation of single-walled carbon nanotubes without human intervention [3] - The formation of these carbon nanotubes is closely related to multiple factors, including micro-meteorite impacts, volcanic activity, and solar wind irradiation, showcasing nature's ability to synthesize key materials under extreme conditions [3] - A comparative study between the Chang'e 6 far side samples and the Chang'e 5 near side samples revealed that the carbon structures in the Chang'e 6 samples exhibit more pronounced defect characteristics, likely due to a more intense history of micro-meteorite impacts on the far side [3] Group 2 - This discovery follows the previous finding of few-layer graphene in the Chang'e 5 lunar samples, representing another important advancement by the Jilin University research team [3] - The research results have been published in the academic journal "Nano Letters," contributing to the scientific community's understanding of lunar material composition and evolution processes [3]
