DESCRIPTION:Speakers: Brittany Kerr (Swinburne University of Technology)\n
 Electrochemical water splitting with a proton-exchange membrane electrolyt
 e provides many advantages for the energy-efficient production of high-pur
 ity dihydrogen in a sustainable manner\, but the current technology relies
  on high loadings of expensive and scarce iridium at the anodes\, which ar
 e also often insufficiently stable in operation. A common strategy to achi
 eve stability is to synthesise composite oxides composed of multiple compo
 nents\, for example [M]SbOx\, [M]PbOx\, [M]BiOx. Yet\, these materials pos
 e a challenge in that it is not well understand how the mixed metal works 
 to stabilise the material under acidic conditions. The present work presen
 ts an efficient ruthenium antimony oxide (RuSbOx) electrocatalyst synthesi
 sed as a thin film on fluorine-doped tin oxide (FTO). Comprehensive physic
 al characterisation by X-ray absorption spectroscopy (XAS) and transmissio
 n electron microscopy (TEM)  reveals important insights into the structure
  and mechanism of the examined materials while simultaneously highlighting
  how structural effects\, such as disorder\, may impact the observation an
 d interpretation of EXAFS data.\n\nhttps://events01.synchrotron.org.au/eve
