Abstract

The nanoalloy structure greatly improves the catalytic activity for electrocatalytic N2 reduction and Suzuki–Miyaura coupling reactions under ambient conditions.

Current Progress of Electrocatalysts for Ammonia Synthesis Through Electrochemical Nitrogen Reduction Under Ambient Conditions

“…In addition, some studies have shown that the catalyst activity can be further increased by using the synergistic effect of the two elements and loading the alloy on a support. Fu et al . successfully deposited bimetallic Pd–Co alloy nanoparticles on CuO nanosheets.…”

“…In addition, some studies have shown that the cata-lyst activity can be further increased by using the synergistic effect of the two elements and loading the alloy on as upport. Fu et al [62] successfully deposited bimetallic Pd-Co alloy nanoparticleso nC uO nanosheets. Due to the synergistic effect, the bimetallic Pd-Co catalyst has higher catalytic activity than the single-metal (Pdo rC o) catalyst.…”

“…The high-intensity deconvoluted peaks in the high-resolution spectrum of Pd 3d at binding energies of 335.8 and 341.1 eV correspond to the 3d 5/2 and 3d 3/2 electronic configurations of metallic Pd in Pd (1%)/CuFe 2 O 4 (Figure 4b). 54,55 The other two low-intensity peaks at binding energies of 336.8 and 342.3 eV are ascribed to the presence of Pd +2 , suggesting that very low concentration of Pd is present as PdO in the sample. 54,55 Similarly, the spectrum of Pd 3d present in Pd (5%)/NiFe 2 O 4 exhibits two sharp peaks associated with the 3d 5/2 and 3d 3/2 electronic configurations.…”

Exploration and Investigation of Periodic Elements for Electrocatalytic Nitrogen Reduction

“…Shen and co-worker developed Pd-Co nanoalloys nested on CuO nanosheets (Pd-Co/CuO) for efficient NRR. [214] At −0.2 V, it achieved 2.16% efficiency with 10.04 µg h −1 mg cat −1 NH 3 yield rate in 0.1 m KOH. The low results may be due to presence of Pd-Co over CuO reducing the active sites of CuO for N 2 selectivity.…”
