Composite electrodeposition of TiO
2 particles in amorphous Ni-Mo alloy matrices was carried out using aqueous citrate solutions (pH5.0) where anatase- or brookite-TiO
2 particles were suspended. A white and uniform composite coating was obtained from a solution containing 200g dm
−3 of TiO
2. The composition of the Ni-Mo alloy matrices remained unaltered with the inclusion of TiO
2. Although the uptake of TiO
2 did not exceed 0.1wt.%, the resulting Ni-Mo/TiO
2 layer exhibited the ability to decompose gaseous NO in the air or Methylene Blue in water. It was suggested that the anti-corrosive ability of the Ni-Mo layer is improved by the inclusion of TiO
2 in the layer.
