Abstract:
Chemical reactions are at the foundation of the physical world. Understanding the chemical interactions gives us better knowledge about the world around us. One way of doing this is by simulating natural occurring reactions with the help of catalysts in electrochemistry. Catalyst can be materials that favor different reactions, depending on their nature and the potential applied at their surfaces. One of the most important aspect that you take into consideration in constructing a catalyst is the active surface, the place near were the interactions take place. A lot of studies have been made in researching different materials with different structures. Sometimes, realizing thin active layers of materials can become difficult and quite expensive. This study is aiming to show a more eco and cheap way that can be used to construct an electroactive layer on a base material with the help of metal reducing microorganisms. This kind of bacteria are versatile microorganisms that can reduce different types of metals and they can be used to do this on the surfaces of electric conductive materials presenting a possible new way of building electrocatalysts.
