Abstract:
The focus of the present thesis is to prepare and characterize surfaces modified with carbon nano-onions (CNOs) to develop electrocatalytic systems and electrochemical (bio)sensors for biomedical and environmental applications. The first part of the Thesis is a related to the dispersibility, electronic structure, surface chemical composition and electrochemical properties of CNOs. In the second part, novel electrocatalytic properties and electrochemical (bio)sensing applications of these materials were also explored to understand their relationship with the electronic structure, of CNOs. The results presented here illustrate the advantages of incorporating CNOs in the design of electrochemical systems to improve their performance. These results might help to fabricate tailor made surfaces and devices with unique properties to realize high potential of CNOs to the maximum and to open new application possibilities in areas such as electrochemical energy storage and electroanalytical methods.
