“…As the electrochemical reactions generally occur on the surface and interface, the structural architecture of the catalysts is another important factor to further promote the electrocatalytic activity or stability. − Among numerous strategies, the construction of heterogeneous interfaces was considered as an important choice owing to the presence of abundant defects and easy charge exchange in the interfacial structure. − Yang et al successfully prepared a Pd/α-MnO 2 electrocatalyst and demonstrated that enhanced interfacial interaction can improve the inherent activity of electrocatalysts where the interface promoted the desorption of intermediate CO and thus boost the activity and stability toward ethylene glycol electrooxidation. − Du et al performed a lot of research on heterogeneous nanomaterials. By regulating the reduction kinetics of Pt 2+ , they realized the growth of Pt nanoparticles (NPs) on Pd NSs and believed that the lower reduction power can lead to the preferential growth of Pt NPs on the edge of Pd NSs, thus causing a downward shift of the d-band center.…”

Creating a heterostructure in electrocatalysts generally can enhance the intrinsic activity during common electrocatalytic reactions. A facile method to synthesize PdCuZn nanoparticledecorated ultrathin amorphous CeO 2 nanowire (NW) heterostructures was realized in an aqueous solution. The CeO 2 introduced in the material has unfilled 4f orbitals and abundant electron energy levels and contains abundant defects and oxygen vacancies, which can strongly interact with other components in the catalyst. At the same time, the ultrathin structure of the NW and the multiple components of the alloy material work together to improve the electrocatalytic alcohol oxidation performance of the catalyst. The electrocatalytic mass activity of the CeO 2 /PdCuZn NW heterostructure toward ethylene glycol oxidation is 7.2 A mg pd −1 and the residual current after the stability test of 5000 s reaches 4.82 A mg pd −1 , indicating the superior intrinsic activity and stability/durability. The heterostructures also possess good antipoisoning ability and electrocatalytic kinetics.

“…It has been reported that Pd is widely used to construct catalysts for polyol oxidation reactions. Pd-based nanomaterials reduce the use of noble metal Pd, which reduces the price of catalysts and improves the cost performance of catalysts. − In addition, since Pd-based catalysts can advance the breakage of the C–C bonds of ethylene glycol/glycerol to a certain extent, Pd-based catalysts show better catalytic performance for ethylene glycol oxidation reaction (EGOR) and GOR. , Therefore, it is imperative to construct a cost-effective Pd-based catalyst …”

The development of efficient and stable Pd-based electrocatalysts is extremely important to facilitate the development of catalysts for polyol oxidation reactions. To synthesize Pd-based catalysts with excellent catalytic performance, a series of PdAg porous nanowires (PdAg PNWs) with different elemental ratios was constructed by facile synthesis using a seed-mediated method. The synthesized PdAg PNWs have a rough surface and a porous one-dimensional structure, which optimize the specific surface area and surface area of catalysts, thereby providing more active sites for catalysts. PdAg PNWs benefited from the geometric effect of porous nanowires and the synergy between Pd and Ag, showing excellent catalysis (8243.0 and 4137.0 mA mgPd –1) for the ethylene glycol oxidation reaction (EGOR) and glycerol oxidation reaction (GOR). Among them, the optimal Pd62Ag38 PNWs show the highest catalytic activity (6.0 times and 3.9 times higher than Pd/C) and stability compared with Pd57Ag43 PNWs, Pd51Ag49 PNWs, and Pd/C for EGOR and GOR. At the same time, this porous one-dimensional structure also endows PdAg PNWs with faster electron transfer capabilities than Pd/C. This work will likely provide an effective strategy for constructing cost-effective catalysts.

Pd-based catalysts are attractive anodic electrocatalysts for direct methanol fuel cells owing to their low cost and natural abundance. However, they suffer from sluggish reaction kinetic and insufficient electroactivity in methanol oxidation reaction (MOR). In this work, we developed a facile one-pot approach to fabricate low Pt-doped Pd 12 P 3.2 nanowires with crystalline/amorphous heterophase (termed Pt-Pd 12 P 3.2 NWs) for MOR. The unique crystalline/amorphous heterophase structures promote the catalytic activity by the plentiful active sites at the phase boundaries and/or interfaces and the synergistic effect between different phases. Moreover, the incorporation of trace Pt into Pd lattices modifies the electronic structure and improves the electron transfer ability. Therefore, the obtained Pt-Pd 12 P 3.2 NWs display significantly enhanced electrocatalytic performance toward MOR with the mass activity of 2.35 A mg Pd+Pt −1 , which is 9.0, 2.9, and 2.0 times higher than those of the commercial Pd/C (0.26 A mg Pd −1 ), Pd 12 P 3.2 NWs (0.82 A mg Pd −1 ), and commercial Pt/C (1.19 A mg Pt −1). The high mass activity enables the Pt-Pd 12 P 3.2 NWs to be the promising Pd-based catalysts for MOR. −1 ), Pd 12 P 3.2 NWs (0.82 A
