Chinese researchers have made a groundbreaking discovery of naturally occurring few-layer graphene in lunar samples brought back by the Chang’e-5 probe. This finding sheds light on the moon's geological activities, evolutionary history, and environmental characteristics. The research team from Jilin University estimates that about 1.9 percent of interstellar carbon exists in the form of graphene, offering valuable insights into celestial bodies' geological evolution and potential resource utilization on the moon. Through Raman spectra analysis, they confirmed the high crystallization quality of graphite carbon in the lunar samples, which also contain iron compounds believed to be linked to graphene formation. The researchers identified the graphite carbon as few-layer graphene, likely originating from mineral catalytic processes influenced by solar wind and early volcanic eruptions on the moon. This research, published in the National Science Review, marks a significant milestone in lunar exploration and contributes to a deeper understanding of the moon's composition and history. The Chang’e-5 mission, which brought back 1,731 grams of lunar samples, has enabled numerous scientific achievements and publications, advancing knowledge in lunar studies.
