Research On Diamond Film Electrodes Appling To Hydrogen Production By Polluted Water

Hydrogen energy has the important strategic status as a clean and effectively reproducible energy when the energy is drying up. It is very important to know about how to explore an economically and low-cost method to produce hydrogen. In a good many methods, electrolysis is broadly applied with its simple equipment, ripe craftwork and high hydrogen purity. But the disadvantage of this method is high energy consume and low efficiency. Besides, traditional electrode can be easily eroded, and easily lost activity. So people often make use of water without iron as material. That way not only increases cost but also wastes much water resource . Especially It is in the area where water is rare. Under the condition, we can electrolysis the polluted water to produce hydrogen. It can save the process of wiping off ion, and economize water resource. It is economical and environment–protected, but it requires higher standard to electrode water.With the development of the deposition technique, people focus on studying the preparation the diamond thin film electrode on some fund. The diamond film has good characters, for example, it has wide potential window, low background current, good catalyzing activity, bearing erosion and high temperature, so it has some characteristics such as high current efficiency, complete decomposition, and little repeating when the diamond film electrode applied to polluted water treatment, especially when applied to waste water treatment with super high COD .Therefore, if we combine the diamond film electrode preparation with polluted water treatment and hydrogen production. It can not only advance energy utilized efficiency, but also can protect environment, economize water resource, which makes it convenient to hydrogen application.The present article introduces the relative knowledge about hydrogen energy, which includes characteristics and application about hydrogen energy, hydrogen production, hydrogen dryness and purification. That emphasizes the different methods of hydrogen production , by comparing their advantages and disadvantages. Then, it introduces the relevant knowledge of diamond film electrode preparation and token, including exploring its growth influence, craftwork parameter etc. Lastly,it studies the electrochemistry character of diamond film, in order to put diamond film electrode in producing hydrogen from polluted water. The experimental result shows that it can availably decompose organic substance and produce high purity hydrogen...
