1.2. Power supply for rail-free movement by using platinum catalytic engine

    The driving force of Biomolecular Rocket is catalytic engine of platinum. This catalytic engine became more powerful^[1],[2], increasing the surface of platinum. Biomolecular Rocket had numerous platinum particles to increase the surface of platinum. In this experiment, we deposited chromium to 1 μm beads which are covered platinum and we make half platinum beads^[3]. Then, we observed a behavior of the beads in 3% H₂O₂ solution. From this experiment, we are able to investigate whether surface area of platinum was related to the speed.
