“…An anodic peak was noted in the reverse scan, which was generated by the removal of the incompletely oxidized carbonaceous species that was formed in the forward scan. [30,42,43] Furthermore, an additional cathodic reduction peak of copper oxide was also observed at À0.25 V for the Pd 56 -Cu 44 /C and Pd 39 -Cu 61 /C samples, which was probably due to the higher copper content in these two catalysts.…”

Monodisperse bimetallic Pd–Cu nanoparticles with controllable size and composition were synthesized by a one‐step multiphase ethylene glycol (EG) method. Adjusting the stoichiometric ratio of the Pd and Cu precursors afforded nanoparticles with different compositions, such as Pd85–Cu15, Pd56–Cu44, and Pd39–Cu61. The nanoparticles were separated from the solution mixture by extraction with non‐polar solvents, such as n‐hexane. Monodisperse bimetallic Pd–Cu nanoparticles with narrow size‐distribution were obtained without the need for a size‐selection process. Capping ligands that were bound to the surface of the particles were removed through heat treatment when the as‐prepared nanoparticles were loaded onto a Vulcan XC‐72 carbon support. Supported bimetallic Pd–Cu nanoparticles showed enhanced electrocatalytic activity towards methanol oxidation compared with supported Pd nanoparticles that were fabricated according to the same EG method. For a bimetallic Pd–Cu catalyst that contained 15 % Cu, the activity was even comparable to the state‐of‐the‐art commercially available Pt/C catalysts. A STEM‐HAADF study indicated that the formation of random solid‐solution alloy structures in the bimetallic Pd85–Cu15/C catalysts played a key role in improving the electrochemical activity.

“…The VO x NT's present several potential technological applications, such as sensing elements [13], catalysis [14] and Li-ion batteries cathodes [15]. In the last case, it was found that the amount of V 4+ in the structure is critical as it affects and reduce notabily the performance of the cathode.…”

“…[217] Pd-V 2 O 5 nanotubes have shown outstanding electrocatalytic properties and long-term stability. [218] Compared with anchoring with the conventional carbon supports, Pt-V 2 O 5 /C composite nanosheets also have dramatically improved catalytic activities. Accompany with the oxidation of alcohols, carbon monoxide (CO) may be generated.…”

Vanadium oxides are known for their multioxidation states and diverse crystalline structures. Owing to their excellent interactions with molecules or ions, outstanding catalytic activities, and/or strong electron–electron correlations, nanostructured vanadium oxides have been extensively studied for energy conversion in the recent years. Here is a review of the recent advances in the development of nanostructured vanadium oxides and their applications. The synthesis strategies and structural properties of various vanadium oxide nanostructures, including vanadium dioxide (VO2), vanadium pentoxide (V2O5), and others, are summarized. The applications of vanadium oxides in energy conversion are discussed, focusing on three important types of energy sources: chemical energy (LIBs, pseudocapacitors and fuel cells), solar energy (photovoltaics and photocatalytic hydrogen evolutions), and heat (thermoelectric generation). Finally, conclusion with our remarks on the prospects of nanostructured vanadium oxides in energy conversion are provided.
