Abstract:
      Both sequential and co-deposition methods based on electroless plating method for preparation of PdAg membranes were investigated. The morphology, phase structure, compositional homogeneity and compactness of the membranes prepared by two methods were compared. Results showed that Pd-Ag co-depositions were dendritic, inhomogeneous, poor compactness, while multi layer sequential depositions were more homogeneous and compact. The multi layer sequential depositions were required higher temperature and longer time for annealing to form Pd-Ag alloy. The Pd particles size was decreased by alternate Ag layer and the surface of Pd-Ag membrane was more smooth.
