Raney-nickel Catalysts Produced by Mechanical Alloying
Raney catalysts were prepared by a combination of mechanical alloying and leaching as an alternative in the synthesis of Raney-Nickel catalysts. Binary Al-Ni and ternary Al-Ni-Fe alloys with nominal compositions Al65Ni35, Al75Ni25, Al65Ni30Fe5, Al75Ni20Fe5 (in atomic percent), were processed from pure elemental powders; they consisted mainly of the intermetallic B2 AlNi phase. Aluminum was sele...
متن کاملInvestigation on Mechanical and Electrical Properties of Cu-Ti Nanocomposite Produced by Mechanical Alloying
In this paper, Cu-Ti nanocomposite synthesized via ball milling of copper-titanium powders in 1, 3, and 6 of weight percentage compounds. The vial speed was 350 rpm and ball to powder weight ratio kept at 15:1 under Argon atmosphere, and the time of milling was 90 h. Obtained powders were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), and dynamic light scattering (DLS)....
متن کاملAging of a nanostructured Zn50Se50 alloy produced by mechanical alloying
The aging of a nanocrystalline equiatomic ZnSe alloy produced by mechanical alloying was investigated using X-ray diffraction (XRD) and differential scanning calorimetry (DSC) techniques. The measured XRD patterns showed that Se atoms located at interfacial component migrated with aging giving raise to a crystalline selenium (c-Se) phase. DSC spectra of heat-treated samples at temperatures abov...

متن کاملMechanical Alloying Synthesis of Co9S8 Particles as Materials for Supercapacitors
Cobalt sulfide (Co9S8) particles are compounded as the electrode materials of supercapacitors by a mechanical alloying method. They show excellent properties including good cycling stability and high specific capacitance. A supercapacitor is assembled using Co9S8 as the anode and activated carbon (AC) as the cathode. It gains a maximum specific capacitance of 55 F ̈g ́1 at a current density of 0....
