What is the carbon anode?
Carbon electrodes are very useful in some electrochemical reactions due to several favorable properties. Electrochemical reactions include electrons transport from one place to another and, if they are conveniently configured, provide useful electric currents. Electricity can be stored, manufactured or consumed in responses used in batteries, production of industrial metals and chemicals, capacitors and fuel cells. The anode has a positive charge and attracts electrons, while the cathode has a negative charge and attracts positive ions. Electric current is replaced by replacement of electrons from the cathode to the anode. Carbon may serve anode or cathode; In both applications, however, carbon is usually combined with other elements to increase the conductivity. Electrochemists think of carbon in their solid states of graphite and similar, almost pure forms of carbon. The carbon connected almost exclusively on other carbon atoms reaches a high degree of delocalizedElectrons that make it a good conductor. The carbon anode is a popular choice in electrochemia for other reasons, including non -mexicity, low cost and flexibility.
The first use of carbon as cathodic material was proven in 1792, when graphite successfully replaced metals in some experimental early batteries. In the battery, the energy is stored in the electrochemical potential of reactants and released as needed.
electronic capacitors made of electric carbon charge between double carbon electrodes of a huge surface area. One side of the double layer acts as a carbon cathode and the other as a carbon anode. The positively charged ions stick to the cathodic side and negatively learn on the anodic side. After release, electrons are released into the circuit.
molded carbon anode made of artificial graphite is used in extensive production of chlorine, aluminum and silicon. ProductionCalcium, yellow phosphorus and ferrollo rbide use carbon anodes. These processes require energy. The carbon anode is gradually consumed in this process and loses carbon like carbon dioxide. The anodes lose efficiency when they degrade, causing the use of metal anode in modern chlorine plant plants.
In the fuel cells, electricity is drawn directly from an anode of electrochemical reaction - a very effective conversion compared to energy generated indirectly through the combustion of fuels for mechanical equipment control. Fuel is usually hydrogen gas and oxidant is oxygen from the air. The cell for mix-catodes cells of anode electrolyte is very thin and is wrapped with more than 400 cells arranged in a series. The carbon anode performs an electrochemical function, but also serves as a way of distraction of precious metal catalysts.
