文摘

Alternative spatial electric field is introduced to improve photocatalytic activity. The photocatalytic efficiency of PMN-PT@TiO2 is improved by about 50%. PMN-PT@TiO2 keep excellent photocatalytic stability even after five runs. Spatial electric field is beneficial to the degradation of both RhB and MB.
