摘要：
This paper details the electrodeposition of metallic molybdenum from an aqueous, acetate electrolyte containing molybdate ions. The deposition is carried out in a highly concentrated (up to 10 M) acetate bath in the presence of a very low concentration of bone glue (60 mu g/L). The molybdenum metal deposits are up to 20 gm thick and adherent. The deposits were characterized by XRD and XPS analysis. The deposition process is very inefficient, as up to 99% of the current is used to generate hydrogen during electrolysis. The effect of acetate concentration, pH, additives and current on the deposition efficiency and physical properties of the molybdenum deposit were investigated and optimized to obtain smooth, adherent coatings.
