Article Synopsis
- The challenge in researching iridium-based water oxidation catalysts is to find a suitable molecular precatalyst that produces clear and effective active species for catalysis.
- Previous work suggested that the resting state of the catalyst might be a μ-oxo-bridged Ir dimer, but the exact structure of the active species remains unknown.
- New findings revealed that a mixture of dinuclear iridium species could effectively catalyze oxygen evolution without needing complex activation steps, paving the way for better understanding and designing efficient active species in future studies.
Terahertz (THz) spectroscopy provides a noncontact method to measure the ultrafast dynamics and photoconductivity of mobile carriers in semiconducting materials. This has proven useful in studying artificial photosynthesis devices which use semiconductor photoelectrodes. We present a brief introduction to optical-pump THz-probe (OPTP) spectroscopy, a technique that provides unique and useful insight into interfacial electron transfer (from the surface-attached dye to the conduction band of the semiconductor) in dye-sensitized photoelectrochemical cells.
