Material characterization and corrosion performance of nickel electroplated in supercritical CO2 fluid

Interaction of Nickel with Carbon Dioxide in [Ni(CO2)n]− Clusters Studied by Infrared Spectroscopy

“…4 Moreover, nickel has been used in a number of electroplating processes involving supercritical CO 2 . 5,6 On a molecular level, conversion of CO 2 to feedstock (e.g., syngas) requires reduction of CO 2 molecules. Kubiak and coworkers have demonstrated that Ni ions embedded in organic frameworks can convert CO 2 molecules to CO 3 2− and CO. 7 We have shown in previous studies that the electronic structure of the metal species has a large effect on the interaction between the metal and CO 2 molecules.…”

“…In this context, nickel has also been shown to be a useful active component of catalysts in dry reforming reactions wherein CO 2 and CH 4 are converted to syngas . Moreover, nickel has been used in a number of electroplating processes involving supercritical CO 2 . , …”

Preparation and characterization of palladium-hydride-coated titanium as a reference electrode for the supercritical carbon dioxide emulsion electrochemical system

“…Shinoda et al also reported that amount of the additive used in copper metallization of nano-scale holes could be reduced significantly by a sc-CO 2 suspension media [14]. In addition, several researches reported that lower surface roughness and smaller grain size of nickel [15] and copper [16] films can be obtained by means of the EP-SCE method in comparison with the case from normal aqueous solutions. Moreover, the pore size distribution of titanium dioxide was found to be more uniform through the electrodeposition with the sc-CO 2 emulsion method [17], and sc-CO 2 demonstrated the ability to control morphology and grain size of the TiO 2 films at the same time [18].…”

Defect-Free Nickel Micropillars Fabricated at a High Current Density by Application of a Supercritical Carbon Dioxide Emulsion

“…15 Properties of Ni electroplated can influence its application in MEMS devices, especially for the mechanical properties. 16 Surface roughness, 17 grain size, 18 hardness, 19 and wear properties 20 of Ni film have been reported to improve significantly when electroplated with Sc-CO 2 -E.…”
