Mo-modified electronic effect on sub-2 nm Ru catalyst for enhancing hydrogen oxidation catalysis

Abstract

The development of efficient and durable hydrogen oxidation reaction (HOR) electrocatalysts is desired but challenged before the commercialization of H2-O2 fuel cell system. In this study, ultrafine RuMo bimetallic particles...

PtIrFeCoNiMo high-entropy alloy nanodendrites for boosting the alkaline hydrogen oxidation performance

“…4b) and all of them are further away from the Fermi level ( E f ) compared with that of Pt. Based on the d-band theory, 50–52 the adsorption energies of intermediates will be weakened with the E d declining, while they can be enhanced with the E d rising, which is able to explain the decrease of HBE on HEA. Further, CV tests of HEA NDs and Pt/C in the Ar-saturated 0.1 M KOH solution were performed to study HBE.…”

V–O Species-Doped Carbon Frameworks Loaded with Ru Nanoparticles as Highly Efficient and CO-Tolerant Catalysts for Alkaline Hydrogen Oxidation

“…Moreover, Ru/VOC also exhibits more excellent HOR performance in comparison with most reported Ru-based catalysts (Figure d and Table S4). ,,− …”

Molecular Catalysis Enables Fast Polyiodide Conversion for Exceptionally Long-Life Zinc–Iodine Batteries

“…Subsequently, the relationship between the rotation speed and current is derived from Figure 3f (Figure 3g). Calculating with the Koutecky−Levich equation, 38,39 the electron-transfer number for I 0 in Zn−I 2 batteries with Hemin catalyst is 0.758, which further demonstrates the conversion mechanism between I − and I 5 − . Based on the above characterizations and analyses, we summarize the chemical adsorption and electrochemical reactions in eqs 1 and 3.…”
