A Cu2S/NiOOH Heterojunction Enables Highly Selective Ammonia‐to‐Nitrite Electrooxidation at Industrially Relevant Current Densities

Advanced Materials, EarlyView.
Cu2S/NiOOH heterojunction enables efficient ammonia electrooxidation coupled with hydrogen evolution. Interfacial electronic modulation of Ni sites promotes selective NH3‐to‐NO2− electrooxidation at high current density. In a membrane electrode assembly, Cu2S/NiOOH maintains over 90% Faradaic efficiency of nitrite at 800 mA cm−2, highlighting its ...

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
