氟化氢溶液无电沉积法制备W掺杂Ag树枝晶

应用无电沉积在氟化氢溶液制备W掺杂Ag树枝晶，样品由XPS，XRD，SEM和TEM表征，结果表明在Ag-W二元体系中，Ag的生长起主导作用，不受钨酸根离子而改变。提出W元素的掺杂方式，即W元素的掺杂是在银的沉积过程中通过化学吸附—钨酸根二聚体的氧原子与银原子的化学作用力而实现的。循环伏安法用于检测银氧间的化学键能的强弱。

Electroless Deposition of W‐doped Ag Dendrites from HF Solution

A simple method was developed for the preparation of W‐doped Ag dendrites by using electroless deposition from hydrofluoride solution. The samples characterized by XPS, XRD, SEM and TEM techniques, show that the growth of silver is leading and can not be changed essentially by tungstate ions in the Ag‐W binary system. A doping mode of W element was proposed, i.e., the doping of W may occur during silver deposition through chemisorption‐chemical bonding of oxygen atoms of tungstate dimer with silver. Cyclic voltammetry was employed to determine the chemical bonding energy between silver and oxygen.
