Abstract:

A convenient method of preparing compounds in the system WO3-xFx is described and the photoelectrolytic behavior of WO3-x and WO3-xFx anodes has been investigated. It was found that the substitution of small amounts of fluorine for oxygen in WO3 does not affect adversely its photoelectrolytic behavior. Moreover, substituted fluorine increases the stability of electrodes of WO 3 when used for the photoelectrolysis of water. Author
