We report a carbonaceous nanomotor with characteristic flask-like hollow structure that can autonomously move under the propulsion of oxygen bubbles. The nanoflask (CNF) motor was fabricated by encapsulating platinum nanoparticles (Pt NPs) into cavity CNF. internally encapsulated Pt NPs act as catalysts to decompose hydrogen peroxide (H2O2) fuel generated bubbles recoil motion CNF motors. Besides, velocity motors be controlled adjusting concentration H2O2 solution. increases increase concentration, up 109.25 μm s-1 at 10% H2O2. This study provides important implications for understanding behaviors nanomotors an internal cavity, and self-propelled smart carrier systems have potential applications in future.
