Abstract

In this study, Pt(0) microscrolls are synthesized on polished Ni via galvanic replacement reaction (GRR). Employing in situ optical microscopy, the dynamic motion of the catalytic microscrolls as micromotors in H₂O₂ solutions is revealed. This method offers a rapid fabrication of scrolls from diverse noble metals and alloys.
