纳米级Au/C催化剂的制备及其DBFC单池性能
Preparation of nano Au/C catalysts and their performance as a direct borohydride fuel cell electrode
摘要
Abstract
Au/C catalysts were prepared by immobilizing the gold sol having a mean particle size of 5. 0 nm with a quite narrow size distribution on carbon nanotubes (CNTs), Vxc-72R or ECP 600JD carbon black. Elec-trocatalytic activities of different Au/C catalysts with and without acid treatment (first with concentrated HC1 then with concentrated HNO3) for the carbon supports for BH-4 oxidation were investigated. The hydrophilicity of all carbon supports and the Brunauer-Emmett-Teller (BET) surface area of CNTs increased, but the BET surface area of Vxc-72R or ECP 600JD decreased after the acid treatment. The Au loading on the carbon supports was closely related to the BET surface area of the supports. Acid treatment of the carbon supports was also an important factor for improving the electrocatalytic activity of the catalysts. Au supported by the acid-treated ECP 600JD exhibited the best electrocatalystic activity for BH-4 oxidation as an anode catalyst for the direct sodium borohydride fuel cell.关键词
