Electrode for selectively adsorbing noble metal and method for selectively recycling noble metal

The invention provides an electrode for selectively adsorbing noble metal. The electrode comprises an electrode body firmed by a carbon-contained material, and protein of bacteria of Tepidimonas is fixed to the electrode body formed by the carbon-contained material so as to form the electrode for selectively adsorbing the noble metal, wherein the noble metal comprises gold, palladium, silver or indium. The invention further provides a method for selectively recycling the noble metal by utilizing the electrode. The electrode for selectively adsorbing the noble metal and the method for selectively recycling the noble metal by using the electrode have the advantage that the adsorption capacity of the electrode can be effectively improved, the adsorption efficiency of the protein can be improved, the gold adsorption time is shortened, the required metal can be effectively and selectively adsorbed, and a high use value is achieved. 本发明提供种选择性吸附贵金属的电极，包括：含碳材料所形成的电极；以及嗜热性碱性蛋白酶生产菌属(Tepidimonas)的菌的蛋白质固定于该含碳材料所形成的电极上，以形
