摘要
In this work, we have demonstrated that with the combination of SnFe2O4 nanoparticles and modified magnetic artificial cilia actuation, a highly efficient photocatalytic activity can be achieved under the visible light. Three different modes of artificial cilia actuation were tested through micro-particle image velocimetry analysis and relation has been established between photocatalytic efficiency and the corresponding vorticity contours generated due to artificial cilia beating. With the optimized artificial cilia rotation, superior performance was achieved with a maximum degradation rate of 81.7% in 60 minutes using the presented design.
