Design of metal-organic frameworks and metal nanoparticles for electrochemical application

Abstract

In order to overcome the disadvantages of metal nanoparticle catalysts, this study was carried out to utilize MOFs. In part 1, we synthesized Pd embedded MOFs to construct a hypothesis using MOFs to protect the Pd catalyst active site and synthesized the materials to confirm the possibility that MOFs could block the active site decay of metal nanoparticles through Li-Air battery test. In part 2, the electrical conductivity was improved by using carbon fiber paper, and the catalytic activity was investigated by oxygen evolution reaction according to MOFs thickness. As a result, it has been confirmed that the thick MOFs can control the catalytic activity by controlling the binding energies of the catalyst and the reactants / products, and can be applied to other metal nanoparticle catalysts. In part 3, MOF was prepared using porphyrin as a ligand to compensate for the disadvantages of porphyrin. In order to utilize the atomic metal redox site, the optimum Cu content, which maximizes the current density was found by controlling the content of Cu through electrochemical carbon dioxide reduction reaction. Thus, in this study, MOFs were used as a solution to overcome the disadvantages of metal nanoparticles, and the possibility was confirmed through the combination of MOFs and metal nanoparticles
