Enhanced catalytic activity of Ru through N modification toward alkaline hydrogen electrocatalysis

Recent Advances in Engineered Ru‐Based Electrocatalysts for the Hydrogen/Oxygen Conversion Reactions

“…As the results shown in Figure 14g, the mass activity and exchange current density of N‐Ru/C in 0.1 m KOH are 4.5 and four times higher than that of Ru/C, respectively. [ 139 ] The effect of phosphating on the HOR catalytic activity of Ru‐based materials is similar to the above N effect. The RuP nanoparticles were successfully constructed on N and O co‐doped 3D porous hollow carbon substrates (RuP/NOC) (Figure 14h).…”

The Role of Hydroxide Binding Energy in Alkaline Hydrogen Oxidation Reaction Kinetics on RuCr Nanosheet†

“…The electrocatalytic performances of amorphous RuCr nanosheets with different molar ratios were tested by a standard three‐electrode system in alkaline electrolyte. [ 30 ] The cyclic voltammetry (CV) curves of RuCr nanosheets in Figure S3a show featured peaks near 0.1 V, depicting surface oxidation of Ru and the stripping of underpotentially deposited hydrogen (H‐UPD). [ 31 ] The IR‐corrected linear sweep voltammetry (LSV) curves of different RuCr nanosheets for HOR in H 2 ‐saturated 0.1 mol/L KOH at 1600 r/min are presented in Figure S3b.…”

Recent progress in metal–organic frameworks (MOFs) for electrocatalysis

“…28 Hydrogen (H 2 ) is a clean, carbon-free energy carrier and a promising alternative for solving energy supply problems in the future. 29,30 The rational and efficient use of hydrogen energy is one of the most pressing issues today. Continuous production of high-purity hydrogen by electrochemical water splitting is a particularly attractive route, but requires efficient and stable electrocatalysts to drive the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in the water splitting process.…”
