Temperature-dependent mechanism evolution on RhRu₃O_x for acidic water oxidation.

ABSTRACT: The oxygen evolution reaction, as the anodic reaction of many electrochemical devices, plays a crucial role in energy conversion. However, the insufficient stability of non-iridium-based materials during the oxygen evolution reaction has severely limited the large-scale application of such devices. Here, using a home-made operando differential electrochemical mass spectrometry system, we show a temperature dependent mechanism evolution effect of RhRu₃O_x in the oxygen evolution process, which highlights the role of temperature in triggering mechanism evolution. This effect enriches the strategies for pathway manipulation. Since different kinetic pathways can influence catalyst stability, this finding suggests that temperature-dependent pathway regulation may serve as a
