Investigation of electrochemical co-deposition of zinc and molybdenum from citrate solutions

► Zn-Mo alloy electrodeposition from citrate baths have been studied. ► It was found that it is possible to electrodeposit Zn-Mo alloy layers from aqueous citrate solutions. ► The optimal conditions for electrodeposition from studied citrate baths are in the narrow pH range of between 4 and 6. ► XPS measurements confirm the presence of metallic molybdenum in obtained deposits. ► The mechanism of Zn-Mo co-deposition has been proposed and discussed.
