    摘要:

    用基于化學(xué)鍍方法的鈀銀共沉積和分步沉積兩種方法制備了PdAg膜。對(duì)比研究了兩種方法制備的鈀銀膜的形貌、相結(jié)構(gòu)、成分均勻性和致密性。實(shí)驗(yàn)結(jié)果表明共沉積法獲得的鈀銀膜是樹(shù)枝狀的、成分不均勻、且致密性很差。分步沉積獲得的鈀銀膜成分均勻、沿側(cè)面生長(zhǎng)趨勢(shì)好,更適合制備超薄致密的用于氫氣分離的鈀銀合金膜。多層分步鍍形成Pd-Ag合金需要更高的溫度和更長(zhǎng)的時(shí)間熱處理。Ag層的交替使得Pd的晶粒減小,并且最終沉沉積的膜表面更光滑。

    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.
