The XPS Analysis of the Electrodeposited Nickel from Ni(CF₃COO)₂-H₃BO₃-HCONH₂ Solution with Thiourea

Abstract

XPS measurements on the surface of nickel electrodeposited from Ni(CF₃COO)₂-H₃BO₃-HCONH₂ solutions with thiourea revealed that nickel is in the form of Ni° and nickel oxides (NiO, Ni₂O₃ etc.), and the sulfur is in the form of NiS, S° and oranic sulfur compounds.
Since nitrogen was not detected on the surface, it appears that no thiourea from the solution is into the electrodeposit.
