This review selectively summarizes the latest developments in the Pd-based cataysts for low temperature proton exchange membrane fuel cells, especially in the application of formic acid oxidation, alcohol oxidation and oxygen reduction reaction. The advantages and shortcomings of the Pd-based catalysts for electrocatalysis are analyzed. The influence of the structure and morphology of the Pd materials on the performance of the Pd-based catalysts were described. Finally, the perspectives of future trends on Pd-based catalysts for different applications were considered.

“…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.

“…Among various metals, nanosize palladium-based catalysts have attracted particular attention due to their special interaction with oxygen and high selectivity for water formation in a multielectron charge transfer process [8][9][10][11][12]. Some recent studies have reported that the combination of palladium with other metals, such as Ni [13][14][15], Fe [15], Sn [16], Rh [17] and Cu [18][19][20][21][22], synthesized by different methods, i.e., co-impregnation [15,18], colloidal synthesis [19], nanotubular mesoporous PdCu by galvanic replacement [20] and electrodeposition of PdCu [22], substantially improves the activity and stability of the alloys. This is attributed to the formation of bimetallic interactions which are stronger than a single metal-oxygen (M-O) interaction, thus generating a bimetallic material with greater stability.…”
