“…In addition to the interests in CO oxidation and electrocatalytic reduction of O 2 over Pd based alloy catalysts, there has also been increasing interest in studies of such catalysts in catalytic oxidation, hydrogenation, and combustion of different hydrocarbons [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][28][29][30][31][32][33] and in catalytic reduction of inorganic ions in solutions. One example of recent interests the catalytic reduction of nitrate pollutants in groundwater from industrial and domestic effluents.…”

Alloying Pd with Cu is important for catalytic reactions such as denitrification reaction and CO oxidation reaction, but understanding of the catalyst preparation and its correlation with the catalyst's activity and selectivity remains elusive. Herein, we report the results of investigations of the preparation of PdCu alloy nanocatalysts using different methods and the catalytic properties of the catalysts in catalytic denitrification reaction and CO oxidation reaction. PdCu alloy nanocatalysts were prepared by conventional dry impregnation method and ligand-capping based wet chemical synthesis method, and subsequent thermochemical activation as well. The alloying characteristics depend on the bimetallic composition. PdCu/Al 2 O 3 with a Pd/Cu ratio of 50:50 was shown to exhibit an optimized hydrogenation activity for the catalytic denitrification reaction. The catalytic activity of the PdCu catalysts was shown to be highly dependent on the support, as evidenced by the observation of an enhanced catalytic activity for CO oxidation reaction using TiO 2 and CeO 2 supports with high oxygen storage capacity. Implications of the results to the refinement of the preparation of the alloy nanocatalysts are also discussed.

“…Moreover, the characteristic diffraction peaks at about 24.8 belong to the graphite (200) plane of carbon support. Besides, no peak is detectable for FeeCo oxide in the Fe 2 CoO x /C precursor, demonstrating that FeeCo oxide is most likely present in the form of the amorphous state [22].…”

“…The catalytic activity of Pd can be modified by alloying with metals having smaller atomic size such as V, Cr, Fe, Co and Ni is particularly effective in enhancing the catalytic activity [16][17][18][19][20][21][22]. Due to the higher electronic density of nickel compared with the other metals in the first transition series, the metallic bond with palladium is stronger which results in increasing and improving the process of catalytic activity [23][24][25][26][27][28][29][30][31]. Ni is the most choice to alloy with Pd to enhance its activity and stability.…”

The modified polyol reduction method was used to prepare a carbon-supported bimetallic PdNi nanoalloys (BMNAs). The prepared catalyst was characterized using X-ray diffraction and transmission electron microscopy. The obtained data indicated that, the average particle size of the alloys in the range & 20-50 nm. The morphology structure shows uniformly distributed particles on the supported carbon surface. The catalytic activity of the compounds for oxygen reduction reaction was investigated by cyclic voltammetry and electrochemical polarization measurements in rotating disk electrodes. As a function of time and calcination temperature, the improved activity and stability were obtained at 300°C for 3 h.
