Real-time oxygen measurements expose hidden losses in solar water splitting

A new technique developed at Imperial College London measures oxygen production in real time, revealing hidden losses in solar water splitting. The researchers found that electrical current did not always correspond to oxygen generation in hematite, one of the most widely studied

A new technique developed at Imperial College London measures oxygen production in real time, revealing hidden losses in solar water splitting. The researchers found that electrical current did not always correspond to oxygen generation in hematite, one of the most widely studied materials in the field, revealing a previously unknown limitation in the reaction.
