Boosting the hydrogen evolution performance of ruthenium clusters through synergistic coupling with cobalt phosphide

Abstract

Synergistic coupling of ruthenium with cobalt phosphide can significantly boost the hydrogen evolution performance of the hybrid catalysts in a wide pH range.

Ruthenium Nanoparticles on Cobalt‐Doped 1T′ Phase MoS2 Nanosheets for Overall Water Splitting

“…[ 45 ] A number of studies showed that Ru nanoparticles deposited on C 2 N, C 3 N 4 , or CoP nanostructures are capable of dissociating water to promote subsequent H + adsorption and recombination into H 2 , resulting in significantly enhanced HER kinetics in alkaline solution. [ 48–51 ] Therefore, the Ru nanoparticles could also be the active sites for HER.…”

Recent Advances on Water‐Splitting Electrocatalysis Mediated by Noble‐Metal‐Based Nanostructured Materials

“…Constructing the interface between Pt with other transition metal compounds has been used as a valid method to tune water dissociation, and then facilitate water splitting process in alkaline solution, where the kinetics of HER occurring at Pt electrode are usually several orders of magnitude lower than those in acidic environments owing to the additional barrier of water dissociation 16. Apart from constructing noble metal/transition metal compound hybrid, some other categories such as engineering nanostructures with controllable sizes and shapes,17 introducing a second nonprecious‐metal element to form alloys on the basis of strain effect and ligand effect, and designing a single atom of noble metal species on the specific support have been found to be effective routes for optimizing the electronic structure, lowering the noble metal loading, and increasing the specific surface area, leading to excellent performance and robust stability for water splitting 18. In all cases, it has been well‐documented that structure‐dependent factors are of great importance in dominating their electrocatalytic performance.…”

Single‐Atom Ru Doping Induced Phase Transition of MoS2 and S Vacancy for Hydrogen Evolution Reaction

“…Ruthenium (Ru) is a 4d transition metal and a member of the Pt group, but its price is about 5% of Pt . Ru is a theoretically suitable alternative to Pt, because it has a hydrogen bond energy (≈65 kcal mol −1 ) similar to Pt‐H.…”

“…Recently, investigators discovered that Ru‐based catalysts can efficiently catalyze HER. Although Ru‐based nanoparticle, cluster and alloy catalysts have been reported to exhibit excellent activity similar to Pt, they do not show the maximum atomic efficiency of Ru…”
