Briefings

Imperial College London researchers developed a real-time oxygen measurement technique to investigate solar water splitting in hematite. The study revealed that electrical current often did not match oxygen generation, indicating a previously unknown limitation in the reaction. This finding suggests significant efficiency losses in the process that were previously unaccounted for.
