Mining in the conquest of space: China finds graphene on the Moon

A discovery of China draws special attention: it is the scientific discovery of graphene of few layers that occurs naturally has been found for the first time in lunar samples brought back by the Chinese Chang’e-5 probe.

According to the team scientific investigation from Jilin University, it is estimated that about 1.9 percent of the total interstellar carbon exists in the form of graphene, whose morphology and properties are determined by a specific formation process. Therefore, natural graphene can provide important reference and information for the geological evolution of celestial bodies and the utilization of in situ resources in the Moon.

In the Landthe high conductivity, resistance and lightness of this material that is extracted from the abundant graphite It has widespread use in sectors such as energy and electronics.

In the case of lunar samples, the team investigation collected Raman spectra, which are used to investigate lunar soils, from areas of the samples moles with a relatively high carbon content, and confirmed that the carbon crystallization quality of graphite in lunar samples it is relatively high.

The researchers discovered that the areas of the soil samples mole that contain carbon also contain compounds of ironwhich researchers believe are closely related to the formation of graphene.

Through observation and analysis, the team investigation confirmed that the graphite form of carbon detected in lunar soil samples is a type of graphene few layers.

The team of scientific investigation confirmed that the formation of few-layer graphene and carbon from graphite may have its origin in mineral catalytic processes induced jointly by the solar wind and the first volcanic eruptions in the moonreports The Global Times.

The research carried out by the researchers from Jilin University and the Institute of Investigation of Metals of the Academy of Sciences of Chinasupported by the Lunar Exploration and Space Engineering Center of the China National Space Administration, was recently published in National Science Review.

A total of 1,731 grams of lunar samples were brought back by the Chang’e-5 mission in December 2020. These samples were the first obtained from a younger region of the lunar surface that contains volcanic rocks. They are also the first samples of extraterrestrial celestial bodies that Chinese scientists bring to Earth. Land.
