PVP-stabilized Ru–Rh nanoparticles as highly efficient catalysts for hydrogen generation from hydrolysis of ammonia borane

“…5) for hydrolysis reaction. This value of activation energy for the hydrolysis of AB is lower than the activation energies reported in the literature for the same reaction using many different catalysts: 52 kJ/mol for RuCu NPs [6], 51.6 kJ/mol for PteCo NPs [17], 51.3 kJ/mol for Cu@Co NPs [20], 54.5 kJ/mol for RuePd@PVP NPs [21], 56.3 kJ/mol for PteRu@PVP NPs [22], and 51.7 kJ/mol for PdePt@PVP NPs [24]; but still higher than 37.2 kJ/mol for NieRu NPs [5], 36.6 kJ/mol for Ru@Ni NPs [8], 38 kJ/mol for CuNi NPs [9], 45 kJ/mol for NiPd NPs [18], and 46.1 kJ/ mol for PdeRh@PVP NPs [23].…”

Very recently, poly(N-vinyl-2-pyrrolidone (PVP))-protected bimetallic nanoparticles, such as rutheniumepalladium [21], platinumeruthenium [22], palladiumerhodium [23], and palladiumeplatinum [24] nanoparticles, have been shown to be highly efficient catalysts for hydrogen generation from boron compounds providing remarkable results.…”

Enhancement of Ag‐Based Plasmonic Photocatalysis in Hydrogen Production from Ammonia Borane by the Assistance of Single‐Site Ti‐Oxide Moieties within a Silica Framework

“…This reaction is of paramount importance because AB has gained significant attention as a potential hydrogen‐storage material by virtue of its high hydrogen content (19.6 wt %), non‐toxicity, solubility, and stability in water at room temperature. In recent years, a combination of various bimetallic nanoparticles, such as FeNi, Pd/Ag, NiPt, Ag@CoNi, Pt–Co@GO, Ru@Co, Cu@Co 3 O 4 , CuCo@MOF, Pt/CNT, and Ni 2 P, have been tested for hydrogen production from AB . In the present study, Ti‐SBA‐15, Ag/SBA‐15, Ag/Ti‐SBA‐15, Ag/TiO 2 /SBA‐15, and physical mixture (Ti+Ag)/SBA‐15 were examined as catalysts for this reaction at room temperature.…”

Nano Metal‐Organic Framework‐Derived Inorganic Hybrid Nanomaterials: Synthetic Strategies and Applications

“…A few NMOF‐derived carbon‐supported binary metal oxides such as ZnFe 2 O 4 /C, CuCo 2 O 4 /C, Co x Fe 3− x O 4 /C, etc., have been reported as an efficient anode material for lithium ion batteries. Enhanced material/electrolyte contact and superior conductivity of electrode materials are attributed to highly porous nature of material and synergistic effects of multiple metal oxides …”
