| Abstract: | The local structure of WO3 photocatalyst in the photoexcited metastable state created 150 ps after laser irradiation have been determined by the pump-probe L3-edge EXAFS and the constrained thorough search analysis. A highly distorted octahedral local structure was found where one of the shortest W-O bonds was further shortened to 1.66 Å while the other five bonds were rather elongated even though theoretical calculations predicted the reverse change. We discuss this contradiction and propose a possible structure for the metastable state. |
