| Popis: | The photoelectrochemical properties of the oxide bronze Ba3Nb4Ti4O21 in NaOH electrolyte have been investigated. Photopotential, photocurrent versus applied voltage and wavelength of radiation, capacitance versus voltage measurements and stability studies of the PEC cell show that the photoanode is stable and yields a photopotential of 700 mV. The band gap, flat-band potential, carrier concentration and minority carrier diffusion length have been estimated. ? 1993. |
