Simultaneous reduction of perrhenate and nickel ions by hypophosphite

  • 107 Accesses

  • 9 Citations

Conclusion

Reduction of water by hypophosphite during Ni-P-Re alloy deposition proceeds in nearly the same proportion as that in the case of Ni-P deposition according to the mass spectrometric analysis of the gas evolved in deuterium-labelled electroless plating solutions. Perrhenate ion is reduced to metal rhenium as shown by the XPS analysis of the electrolessly deposited Ni-P-Re coating. Atomic hydrogen is expected to tkae part in perrhenate reduction at the catalyst surface resulting in a high hypophosphite efficiency in the overall electroless Ni-P-Re deposition process.
