Facile Synthesis of PdCu Echinus‐Like Nanocrystals as Robust Electrocatalysts for Methanol Oxidation Reaction

“…The shifts are caused by the donation of electrons from Cu atom to Pd atom. And it suggests the downshift of d‐band center, which can promote desorption of carbon oxide on the surface of Pd …”

“…And it suggestst he downshift of d-band center,w hich can promote desorption of carbon oxide on the surfaceofPd. [38,51] In order to study the formation process of echinus-like PdCu NCs, the products collected in different times were characterized by FE-SEM.A ss hown in Figure S1(a), the nanoparticles with an average size of 50 nm were formed in the first half hour.A fter 1houro fr eaction, the size of the particles was increased and numerouss hort branches can be clearly observed in PdCu NCs (Figure S1(b)). After 2hours of reaction, the uniform echinus-like nanostructures were generated ( Figure S1(c)).…”

Three-Dimensional PdPtCu Nanoalloys with a Controllable Composition and Spiny Surface for the Enhancement of Ethanol Electrocatalytic Properties

“…into electrical energy, have attracted extensive attention. While their large-scale production and applications are limited by the reaction kinetics and stability associated with catalysts for the oxidation of alcohol. − Pt and Pt-based nanomaterials (NMs) have attracted widespread interest as electrocatalysts for DAFCs because of their unique electrocatalytic performance. − However, the price of Pt is skyrocketing for its scarce reserves, and it is easily poisoned by the carbonaceous intermediates during the reaction . These issues seriously limit the practical applications of Pt catalysts in DAFCs. , …”
