中文摘要:
      用基于化学镀方法的钯银共沉积和分步沉积两种方法制备了PdAg膜。对比研究了两种方法制备的钯银膜的形貌、相结构、成分均匀性和致密性。实验结果表明共沉积法获得的钯银膜是树枝状的、成分不均匀、且致密性很差。分步沉积获得的钯银膜成分均匀、沿侧面生长趋势好,更适合制备超薄致密的用于氢气分离的钯银合金膜。多层分步镀形成Pd-Ag合金需要更高的温度和更长的时间热处理。Ag层的交替使得Pd的晶粒减小,并且最终沉沉积的膜表面更光滑。
The synthesis of Pd-Ag membranes by the multi layer sequential method using electroless plating method for H2 separation
英文关键词:Pd-Ag membrane  Electro- less plating method  Co-deposition  Multi layer sequential method
英文摘要:
      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.
