Ru monolayer island doped MoS2 catalysts for efficient hydrogen evolution reaction

Recent Advances and Perspectives in Ru Hybrid Electrocatalysts for the Hydrogen Evolution Reaction

“…In the example described above, the Ru MI catalyst was synthesized using high-gravity technology, which improved the atomic utilization efficiency of the catalyst and provided a high density of active centers to promote the HER. 83 (2) Lack of a deep mechanistic understanding of hybrid electrocatalysts and their roles during catalysis: Although abundant related studies have been reported, the understanding of factors, such as synergistic effects, strain effects, and electronic effects, is still insufficient. Moreover, reasonably choosing the combination of different metals to maximize the influence factors would be helpful for the development of a hybrid catalyst.…”

Surface distortion of FeRu nanoparticles improves the hydrogen evolution reaction performance in alkaline media

“…19,33,34 Since catalytic reactions properly occur at the lower coordination atomic sites, such as edges, corners, and kinky sites, the formation of surface vacancies would inevitably present such active sites. 35–42 For instance, Yu and co-workers reported that the strain- and defect-engineered Ni-MoS 2 monolayer exhibits a superior HER performance by promoting the rate-determining water dissociation step. 39…”

“…19,33,34 Since catalytic reactions properly occur at the lower coordination atomic sites, such as edges, corners, and kinky sites, the formation of surface vacancies would inevitably present such active sites. [35][36][37][38][39][40][41][42] For instance, Yu and co-workers reported that the strain-and defect-engineered Ni-MoS 2 monolayer exhibits a superior HER performance by promoting the rate-determining water dissociation step. 39 Inspired by the aforementioned concepts, we designed Rubased alloy nanoparticles (NPs) with a distorted surface structure in order to boost the HER kinetics in alkaline media.…”

Oxalate metal–organic framework derived atomic Ru3+-doped Co(OH)2nanosheets for a highly efficient hydrogen evolution reaction

“…[4][5][6] Recent studies showed that some atomic Ruloaded materials displayed considerably higher catalytic activity than the Pt-based materials. [7][8][9][10] For instance, the Tan group anchored single-atom Ru on sulfur vacancy-rich MoS 2 with a Ru content of ∼8.0 at%, which exhibited an overpotential of 30 mV at 10 mA cm −2 in 1.0 M KOH. 11 Chen et al atomically dispersed Ru on Ni(OH) 2 nanoribbons with a Ru content of ∼7.7 wt%, which required a small overpotential of 16 mV at 10 mA cm −2 in 1.0 M KOH.…”
