A series of nano PdFe alloy film electrodes with different ratios were prepared by high-vacuum magnetron sputtering under the action of high-strength magnetic field. Among them, the Pd3Fe alloy film electrode possesses the best hydrogen evolution activity, which significantly changes the properties of hydrogen adsorption (Had) and absorption (Habs) of Pd. Pd3Fe is a nanoassembled film, which consists of many tiny nanosheets connected together. The electrochemical surface area of Pd3Fe electrode is 13 and 7 times that of the Pd/C and Pd electrod...
