Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

Advanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.

Similar Topography and Crater Retention Record yet Divergent Space Weathering Extents across Reiner Gamma on the Moon

The Planetary Science Journal
Electrostatic levitation and migration of charged dust may occur during the formation of lunar swirls. Due to interaction between crustal magnetic anomalies and solar wind, immature fine-grained particles are predicted to preferentially migrate to bright
