Dynamically driven perovskite La-Fe-modified SrTiO nanocubes and their improved photoresponsive activity under visible light: influence of alkaline environment.

Visible-light active La-Fe-SrTiO (LaSrFeTiO) photocatalysts were synthesized via a dynamic hydrothermal route under different NaOH concentrations (2, 3, 4, 5, and 6 M). The results showed that altering NaOH concentrations changed the physicochemical characteristics of the materials. Namely, the decrease in particle size was observed when the NaOH levels were increased.
