Abstract
The photoelectrochemical behaviour of oxide bronzes of the type A(6)Nb (8)Ti(2)O(30) (A = Ba, Sr) has been studied. They show good photoactiv ity with photopotentials of the order of 700-800 mV. The fiat band pot ential hds been estimated to be -0.9 V vs SCE. The band gap estimated from the spectral response is 3.1 eV.
