Redirecting dynamic structural evolution of nickel-contained RuO2 catalyst during electrochemical oxygen evolution reaction

Order–disorder engineering of RuO2nanosheets towards pH-universal oxygen evolution

“…3a, the Raman modes located at 505, 620, and 685 cm −1 , which are observed from a/c-RuO 2 /CC, c-RuO 2 /CC, and a-RuO 2 /CC, are attributed to RuO 2 . 42,43 It should be noted that both a/c-RuO 2 /CC and c-RuO 2 /CC enable the more intensive Raman-active modes at 505 and 620 cm −1 , with regard to a-RuO 2 /CC, which is explained by the rich local lattice imperfections and the characteristic of short-range order in a-RuO 2 /CC. 28 XPS was employed to investigate the effects of phase change on the chemical state.…”

Interfacial electron transfer in heterojunction nanofibers for highly efficient oxygen evolution reaction

“…The (001) plane of SCFR perovskites with and without RuO 2 was chosen as a surface model and Ru is selected as the adsorption site according to the previous studies. [48][49][50] The four-electron reaction pathway in alkaline media is displayed in Fig. 6a and Fig.…”

Nanostructured IrOx supported on N-doped TiO2 as an efficient electrocatalyst towards acidic oxygen evolution reaction

“…[9][10][11][12][13] The oxygen evolution reaction (OER) occurring on the anode side of a water electrolyzer dominates the overall efficiency because of the sluggish kinetics. 12,[14][15][16] At present, Ir and Ru oxides are still the most representative OER electrocatalysts, especially the Ir oxide with more prominent practical potentiality, regrettably, extremely low reserve of Ir element in the earth's crust (0.001 ppm) impedes its widespread application. [17][18][19][20][21] Hence, reducing the Ir consumption without compromising the OER catalytic performance is highly paramount.…”
