Lanthanum-doped sodium tantalate was synthesized by solid state method at low temperature and short calcination time. Pure phase powders were obtained after calcination at 950°C and 1000°C for 1h with average crystal size below 150 nm. The photocatalytic performance was increased with La concentration, reaching a maximum at 2 mol% La. Good activity was observed even without any loading cocatalyst. After further calcination, there was no evidence of improvement of the photocatalytic performance |
