“…Metal nanowire or nanotube array architecture can be a potential substrate to improve noble metal utilization efficiency [176]. Besides it can act as a template, which means that no stabilizer is required, it also serves as an excellent current collector.…”

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.

“…(1) The 3D nanostructure catalyst having large active catalytic surface area could provide high population of the active sites for catalytic reactions, so as to enhance the electrocatalytic activity. Moreover, this 3D structure of NFs can also inhibit the undesirable agglomeration of the active sites [44]. (2) The interconnected structures in nanoflowers also can provide a faster electron transfer, which is favor for the enhancement of Pt electrocatalytic property.…”

“…9,10 Relative to spherical Pt nanoparticles (NPs), Pt nanowires, nanocubes, and hollow nanocubes exhibit higher ORR performances in direct methanol fuel cells (DMFCs) [11][12][13][14] , mainly 45 because they provide more active sites (higher surface energy) for ORR. 16 Pd-M (where M = Fe, Co, Ni, Zn, Cu, and Au) based bimetallic alloys are particularly interesting because they can induce strain and 50 ligand (electronic) effects (electrical coupling between the overlayer and its supporting substrate) to induce high catalytic activity for glucose oxidation reaction and ORR. 16 Pd-M (where M = Fe, Co, Ni, Zn, Cu, and Au) based bimetallic alloys are particularly interesting because they can induce strain and 50 ligand (electronic) effects (electrical coupling between the overlayer and its supporting substrate) to induce high catalytic activity for glucose oxidation reaction and ORR.…”

A facile and one-pot wet chemical approach has been applied for the preparation of palladium copper (PdCu) nanosponges (NSs) through the reduction of Pd 2+ and Cu 2+ ions with L-ascorbic acid in the presence of sodium dodecyl sulfate (SDS) at 95 °C. The PdCu NSs prepared in the presence of 12.5, 25, and 37.5 mM SDS have sizes of 46.0 ± 4.3, 36.8 ± 4.5, and 37.2 ± 2.6 nm, respectively. Relative to a Pd NPs electrode (0.33 mA cm −2 ), Cu NPs electrode (0.31 mA cm −2 ), commercial Pd/C electrode (0.34 mA 10 cm −2 ) and Pt/C electrode (0.66 mA cm −2 ), PdCu NS-modified electrodes provide high current density for oxygen reduction reaction (1.93 mA cm −2 ) under alkaline conditions. In addition, the PdCu NS-modified electrodes provide high catalytic activity for glucose oxidation at −0.01 V vs. Ag/AgCl and are stable even after sweeping for 43200 s in 0.1 M NaOH containing 0.1 M glucose. The higher catalytic activity of the PdCu NSs is mainly due to their greater electroactive surface area (EASA) and synergistic effect 15 caused by the intimate contact between Pd and Cu. The PdCu NS-modified electrodes exhibit high sensitivity (1560 µA mM −1 cm −2 ), good selectivity, and fast response to glucose over a linear range of 0−30 µM (R 2 = 0.997), with a limit of detection (LOD) of 4.1 µM. Having the advantages of good stability, excellent electrocatalytic activity, and cost effectiveness, the PdCu NSs hold great potential for use in fuel cells using methanol or ethanol as fuel and for the fabrication of electrochemical sensor for the 20 detection of glucose in blood samples.
