Abstract
A bubble propulsion model based on catalyzed hydrogen peroxide decomposition and momentum change via O 2 bubbles detaching from the catalyticsurface is proposed to explain the autonomous motion of catalyticnanomotors. The propelling force closely depends upon the surface tension of the liquid as well as the bulk concentration of hydrogen peroxide, and the model predictions are supported by the experimental data of Pt-coated spherical silica microbead motors.This publication has 24 references indexed in Scilit:
