Photo‐induced Intercalation of Cobalt(II) Tellurium Oxide as an Oxygen Evolution (Photo)electrocatalyst

Year: 2024

Type: article

Abstract: The inside cover picture highlights the ability of cobalt(II) tellurium oxide (CTO) to intercalate electrolytic potassium ions upon photo-induced charge separation, thereby stabilising the excited electron, whilst also driving the oxygen evolution reaction by oxidising hydroxide ions. It is shown that the photo-electrocatalytic (PEC) current is about double that of the electrocatalytic (EC) current while the EC current, subsequent to the termination of illumination, is almost as high as the PEC current. This exhibits the ability of CTO to deintercalate and release charge after the termination of illumination.
