Cu–Ni materials prepared by mechanical milling: Their properties and electrocatalytic activity towards nitrate reduction in alkaline medium

Methane decomposition using Ni–Cu alloy nano-particle catalysts and catalyst deactivation studies

“…4(b). The actual composition of alloys was calculated based on the experimental lattice parameter [48,49]. EDX was also used to analyze the actual composition and a comparison of actual Ni-Cu-1…”

Composition-dependent sintering behaviour of chemically synthesised CuNi nanoparticles and their application in aerosol printing for preparation of conductive microstructures

“…CuNi alloys containing about 40wt.% Ni possess a low temperature coefficient of resistivity [1] and they are commonly used for resistive applications [2]. Literature perusal reveals diverse physical and chemical methods of synthesis, such as plasmachemical re-condensation [3], mechanical milling [4,5], diol-and polyol reduction methods [6,7], hydrothermal reduction [8][9][10], sol-gel process [11,12], electrochemical methods [13][14][15][16], metal atom-solvent co-condensation [17], microemulsion technique [18][19][20], reduction of precipitated copper and nickel compounds [21,22], combustion reactions [23,24], etc. for the preparation of CuNi bimetallic and alloy nanoparticles.…”

Elaboration by high-energy ball milling of copper/palladium composite materials – characterization and electrocatalytic activity for the reduction of nitrate in alkaline medium

“…It has been successfully applied to the synthesis of various materials such as magnetic, tribologic, superplastic, catalytic and hydrogen storage materials [1][2][3]. This technique was also used for the development of electrocatalysts for various applications such as nitrate electroreduction [4,5], hydrogen evolution [6], nickel-metal hydride batteries [7] and fuel cells [8]. For instance, we have recently evaluated the influence of the ball milling treatment on the electrochemical activity of pure Cu [4] and Cu-Ni alloys [5] for the reduction of nitrate in alkaline solution.…”
