Low Ru loading RuO2/(Co,Mn)3O4 nanocomposite with modulated electronic structure for efficient oxygen evolution reaction in acid

Modulating the Electronic Structure of RuO2 through Cr Solubilizing for Improved Oxygen Evolution Reaction

“…By comparing published literature, weaker adsorption of Ru and O would lead to lower free energy for the RDS and exhibit excellent OER activity, which matches up with our calculations. [5,42] In addition, after incorporation with Cr, more unoccupied states are produced in the e g state of Ru. [43] This is further supported by the DFT calculated partial density of states results for Ru sites on the surface (Figure S21b, Supporting Information).…”

Bifunctional WC‐Supported RuO2 Nanoparticles for Robust Water Splitting in Acidic Media

“…), revealing the superior utilization of Ru than other Ru-based electrocatalysts in acidic media (Figure 4c and Table S4, Supporting Information). [53,[58][59][60][61][62][63][64][65] To the best of 4f). The RuO 2 -WC NPs exhibit a C dl value of 17.9 mF cm À 2 , which is 2.3-fold higher than that of Ru-WC NPs (7.9 mF cm À 2 ) and 4.97-fold higher than that of WC NPs (3.6 mF cm À 2 ), suggesting a more electrochemical active surface area to expose abundant of active sites.…”

An indium-induced-synthesis In0.17Ru0.83O2 nanoribbon as highly active electrocatalyst for oxygen evolution in acidic media at high current densities above 400 mA cm−2

“…S11†). What is even more remarkable is that among the most recent ruthenium-based acidic OER electrocatalysts reported in 2021 (Table 1), 44–49 In 0.17 Ru 0.83 O 2 -350 has the highest mass activity (1094.90 A g Ru −1 @ η = 300 mV) and the lowest Tafel slope of 32.62 mV dec −1 (Fig. 3b, S12 and Table S5†).…”
