production of personal care products containing plastic microbeads. However, due to the persistence of micoplastics, the threat will still be here for long time even if all the countries banned the microbeads products. In this manuscript, we present a photocatalytic TiO2 based micromotor, Au@Ni@TiO2 for microplastics removal. This catalytic micromotor can move efficiently both in peroxide and water under UV illumination owing to the photocatalytic reaction occurring on the particles. Moreover, novel assembled chains can be formed by individual particles under external magnetic field.
