Title: Water oxidation catalyst using self-assembly including histidine
Inventor: LEE SANG YUP
IPC: B01J31/18
Filed: 2018-04-24
Abstract: A research on water oxidation catalysts producing oxygen through water decomposition is a field of fuel cell development and the development of molecular catalysts for enhancing the efficiency thereof is being actively conducted. Molecular catalysts have high reactivity, but are not enough for industrial applications because of instability and complex synthesis. Therefore, various researches have been made to increase the reaction rate and stability of catalysts through attempts to find and immobilize electron-donating ligands suitable for the catalysts. In the present invention, as a part of the development of an oxygen-producing molecular catalyst, a catalyst in which iridium ions are bonded to a self-assembly of an amphiphilic molecule including a histidine reactor has been developed. As a result, it was confirmed that an imidazole functional group of histidine acts as an electron donor to serve as an effective ligand for iridium ions. In addition, the reaction rate and stability of the catalyst are effectively improved as activation sites of the molecular catalyst are self-assembled.
