 The researchers found that a non-firmly liquid material called Hg2-R2O7 has a remarkable ability to catalyze the oxygen-evolution reaction OR. This material has a high current density and excellent durability, which is attributed to its unique combination of localized debans and metallicity. These properties make it an ideal candidate for use in rechargeable metal-air batteries and direct solar water splitting applications.
