Preparation of Pd-Au membranes

22 SEM images of the surface of Pd-Au alloys (75.8% Pd in the bulk) taken after Hj absorption/desorption experiments (Lukaszewski and Czerwinski, 2003). 

Su et al. (2004) also electroplated Pd-Au alloy in an ambient temperature ionic liquid electrolyte, l-ethyl-3-methylimidazolium chloride tetrafluo-roborate system (EMI-C1-BF4), containing Pd (II) and gold (I). Compact alloy deposits were obtained with galvanostatic electrolysis. The Pd content 

Although the electroplating technique has been used to deposit Pd-Au films, it suffered from the formation of micro-cracks and has not been extensively used for Pd-Au alloy membrane preparation for hydrogen separation.
