Abstract: The present invention discloses a rose petal effect-based biomimetic electrode and a membrane-less water electrolysis reactor utilizing the same, belongs to the technical field of catalytic technology for water electrolysis. The electrode has a surface exhibiting a microscopically alternating hydrophilic-hydrophobic periodic structure. The hydrophilic parts ensure good contact between the catalyst and the electrolyte solution, thereby guaranteeing the electrode's catalytic performance. The hydrophobic parts allow the gas generated at the electrode surface to be discharged through internal porous channels, preventing the formation of visible bubbles on the electrode surface and thereby fundamentally avoiding issues caused by bubble formation. The membrane-less water electrolysis reactor utilizing the electrode can eliminate bubble formation on the electrode surface, thereby avoiding problems related to bubble covering catalytic sites, bubble resistance, and gas mixing. Additionally, it reduces electrolyte resistance loss, making the performance of the membrane-less water electrolysis reactor approach that of membrane electrode reactors.
