Titanium dioxide (TiO2) possesses high photocatalytic activity, which can be utilized to-power the autonomous motion of microscale objects. This paper presents the first examples of TiO2 micromotors and micropumps: UV-induced TiO2 reversible microfireworks phenomenon was observed and diffusiophoresis has been proposed as a possible mechanism.
