Abstract
The movement of catalytic micromotors is often accompanied by gas generation. Currently, the prevailing view is that bubbles play a significant role in their movement. Analyzing the movements of catalytic manganese-based micromotors in a solution of hydrogen peroxide, we found that the reactive force cannot play a significant role in their movement, and the main mechanism occurs due to self-diffusiophoresis.
