摘要：

The application of an external electric field is one of the most efficient approaches for photo-induced charge separation. However, the application of the electric-field- enhanced charge separation is limited in powder catalysts. In this study, the electromagnetic induction derived micro-electric potential in metal-semiconductor core-shell hybrid nanostructure was used to enhance charge separation in the shell semiconductor photocatalysts. The efficiency of photocatalytic hydrogen production can be improved around 110% by utilizing a core-shell nanostructure with a permanent magnet that moves under the normal photocatalytic reactor device. This electromagnetic induction derived electric field via the metal-semiconductor core-shell structure shows efficient conversions from relative motion to electric potential that provide a new opportunity to enhance photocatalytic performance with non-contacted interaction.
