The Formation of RuO_2 Structures on Cladosporium Cladosporioides Hyphal and an Investigation of their Properties

Öz

In this study, ruthenium oxide (RuO₂) was grown on Cladosporium Cladosporioides hyphal using a chemical precipitation method. The morphological characteristics of the material obtained by chemical precipitation method were determined by Scanning Electron Microscope (SEM); its surface area by Brunauer-Emmett-Teller (BET) equipment and its electrochemical properties, such as charging–discharging, cyclic voltammetry (CV) and electrochemical impedance characteristics, using a Gamry 3000 potentiostat system.
