Abstract

A platinum-based nano catalyst supported carbon nano tube electrode and a manufacturing method thereof, more particularly to a manufacturing method of a carbon nano tube electrode and a carbon nano tube electrode supported with the platinum-based catalyst by growing the carbon nano tube on the surface of the carbon paper and using a CVD method on the surface of the carbon nano tube. By growing the carbon nano tube directly, the broad surface area and excellent electric conductivity of the carbon nano tube can be utilized maximally, and especially, the nano catalyst particles with minute sizes on the surface of the carbon nano tube by using the CVD method as a supporting method of the platinum-based catalyst on the surface of the carbon nano tube, the amount of the platinum can be minimized and still shows an efficient catalyst effect and by improving the catalyst activity by increasing the distribution, so academic and industrial application in the future is highly expected.

Description

technical field [0001] The invention relates to a manufacturing method of growing carbon nanotubes on the surface of carbon paper, and then loading platinum nano-catalysts thereon by a chemical vapor deposition (CAD) method, and the platinum nano-catalysts manufactured by the manufacturing method. Specifically, nickel, cobalt, iron or their mixtures are loaded on the surface of carbon paper that has been treated with acid to enhance its wettability by means of ultrasonic or electrochemical treatment, and then carbon sources flow into it to grow carbon nanotubes. At the same time, the carbon nanotubes grown on the graphite surface by the above method are treated with acid, and then the nickel, cobalt, iron or their mixture components are removed and the surface structure is improved. Finally, a chemical vapor deposition method in which gas-phase platinum electric spheres are selectively attached to defects of carbon nanotubes is finally used to support platinum nanocatalysts on...

Problems solved by technology

[0011] However, it can be seen from the above that although there are many methods in the existing technology to try to use carbon nanotubes for fuel cell electrodes, so far , there is no example about the method of directly growing carbon nanotubes on carbon paper, and then effectively loading platinum catalyst particles on the surface of carbon nanotubes according to the nanoscale, that is, using the chemical vapor deposition method
