Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Tailoring Iron Nanostructures on MoS2: The Pivotal Role of Sulfur Vacancies in Growth Morphology and Charge Transfer

Advanced Materials Interfaces, EarlyView.
The deposition of Iron on pristine MoS2/Au(111) monolayers produces nanoparticles that donate charge to the support, generating Fe+2‐interfacial species. On the contrary, on defect‐engineered MoS2, sulfur vacancies trap sub‐nanometric Fe clusters and host two excess electrons that redistribute locally, suppressing Fe oxidation without formal Mo ...
