摘要： The light-driven micromotor has been demonstrated to have great potential in the environmental remediation field. However, it is still challenging to develop highly efficient, eco-friendly and visible light powered micromotors for organic pollutant degradation. In this paper, we report a eco-friendly micromotor based on iron phthalocyanine (FePc) and gelatin, which exhibits the visible light driven self-propulsion behavior using water fuel based on the photocatalytic reaction and self-diffusiophoresis mechanism. Fast motion behavior is observed which induces the rapid agitation of the solution. This, together with the excellent photocatalytic activity, makes the FePc based micromotor highly efficient when utilized in the degradation of organic pollutants with a normalized reaction rate constant of 2.49×10-2 L m-2 s-1, which is by far the fastest and is far superior than the stationary counterpart. The external fuel-free propulsion and the high efficiency in pollutant degradation make the current micromotor potentially attractive for environmental remediation.
