Abstract
The photoelectrochemical behaviour of oxide bronzes of the type A6Nb8Ti2O30 (A = Ba. Sr) has been studied. They show good photoactivity with photopotentials of the order of 700-800 mV. The flat band potential has been estimated to be - 0·9 V vs SCE. The band gap estimated from the spectral response is 3·1 eV. © 1994 Indian Academy of Sciences.
