Multicomponent rotational nanomotors consisting of Pt-coated TiO2 nanoarms grown upon approximate to 2.01-mu m-diameter silica microbeads designed by dynamic shadowing growth are presented. When exposed to H2O2, the structures rotate about an axis through the center of the microbead and perpendicular to the TiO2 nanoarm at a rate of 0.15 Hz per % H2O2 concentration. The rotational frequency increases parabolically when the surface tension of the solution is altered by the addition of sodium dodecyl sulphate; both relationships are explainable by a nanobubble-ejection model.
