Epitaxial growth of Pt–Pd bimetallic heterostructures for the oxygen reduction reaction

Large Au@Pd/PdOx core–porous shell nanoparticles as efficient ethanol oxidation electrocatalysts

“…For example, Zhang et al reported Pd-based NCs with enhanced electrocatalytic activity and stability for EOR and formic acid oxidation reaction. 8–10 However, the catalytic performance of Pd NCs in EOR needs to be further improved for practical DEFC applications. For this purpose, it has been shown that coupling Pd with other suitable metals to form Pd-based bimetallic nanoparticles (NPs) with certain morphologies is an effective strategy.…”

A universal strategy for green and surfactant-free synthesis of noble metal nanoparticles

“…26 The half-wave potential is a critical indicator to appraise the performance of an electrocatalyst, in particular for the ORR. 27 The half-wave potential of Pt-NPs/C is 0.879 V, which is 24 mV more positive than that of Com Pt/C (0.855 V), confirming its higher catalytic activity. The calculated electron transfer number of Pt-NPs/C is ∼ 3.9 (Fig.…”

Engineering organic polymers as emerging sustainable materials for powerful electrocatalysts

“…In addition, the incorporation of amino groups adjacent to the porphyrin cobalt centres in a MOF can also substantially promote the CO 2 RR while simultaneously inhibiting the HER. 272 The positioned amino groups, although not in immediate proximity to the active centre, function as hydrogen-bonding donors, which helps stabilize the intermediate Co–CO 2 adduct and suppresses the formation of the Co–H 2 O adduct.…”
