Low content Ru-incorporated Pd nanowires for bifunctional electrocatalysis

Abstract

The catalytic activity of Pd nanowires with low Ru contents showed superior bifunctional electrocatalytic performance towards both ORR and HER compared to the benchmarking Pt/C.

Controlled synthesis of trimetallic nitrogen-incorporated CoNiFe layered double hydroxide electrocatalysts for boosting the oxygen evolution reaction

“…Currently, noble metals and noble metal-based oxides (especially Ru, Ir, and their oxides) 5,6 are considered the most effective electrocatalysts for water splitting, but they are unavailable for large-scale application owing to their high cost and low natural abundance. 4 Over the past decades, tremendous progress has been made in transition metal-based electrocatalysts, such as metal oxide, 7,8 metal phosphide, 9 and metal chalcogenides.…”

Bifunctional Nanostructured Palladium/MoSx Electrocatalyst for Cathode Hydrogen Evolution Reaction PEM Water Electrolysis and Oxygen Reduction Reaction

“…In this frame, porous Pd nanoparticle assemblies demonstrated excellent performance for both HER and ORR. [ 29 ] In the work of Kweon et al., [ 30 ] low content Ru‐incorporated Pd nanowires (Ru fraction at 1.4 wt%) exhibited excellent electrocatalytic activity for either HER or ORR. Similarly, Pd 0.83 Ir 0.17 3D hierarchical assemblies have been shown to serve as efficient electrocatalysts for both HER and ethylene glycol oxidation reaction.…”

Laser induced trace doping of Pd on Ru nanoparticles for an efficient hydrogen evolution electrocatalyst

“…7,14,15 Palladium (Pd) has a good hydrogen storage function, which can change the electronic structure of Ru atoms and reduce the adsorption and reaction barriers of H and OH. [16][17][18][19] It has been demonstrated that hybrid Ru/Pd electrocatalyst systems can provide a balance between ΔG H (the adsorption energy of H) and favourable active sites, promoting their catalytic performances. However, the doping amount of Pd element needs to be at a low level, and there is currently a lack of controllable trace Pd doping methods.…”
