A new approach to obtain nanostructured nickel deposits on the surface of dielectrics by direct laser writing

摘要

Nanostructured nickel deposits can be applied in hydrogenation reactions catalysis and electrochemical systems development. Laser-induced liquid-phase metal deposition allows creating microscaled nickel structures with a developed surface. In this paper a possibility of abandoning technologically imperfect plating solutions containing various reducing agents such as hypophosphite, boron hydride is shown. Deposition was conducted from solutions only containing nickel salt and various organic ligands which allow avoiding phosphorus and boron codeposition. Influence of ligand nature, ligand concentration and solution pH on laser deposition results was studied. Obtained deposits were researched using SEM, EDX, XRD methods.
