Ultrathin Nanobelts as an Excellent Bifunctional Oxygen Catalyst: Insight into the Subtle Changes in Structure and Synergistic Effects of Bimetallic Metal‐Organic Framework

Abstract

In the published version of our articles, the details for Figure 3d,e are incorrect; absence of satellite peaks of R2 in Figure 3d. When processing the XPS data, the authors misarranged the order of R1 and R2, resulting in errors. The correct details for Figure 3d,e is changed as follows: Figure 3. XPS spectrum of the: a) survey; b) C 1s; c) O 1s; d) Co 2p, and e) Ni 2p.

Regulating the Surface Electronic Structure of RuNi Alloys for Boosting Alkaline Hydrogen Oxidation Electrocatalysis

“…The peaks at 466.0 and 487.0 eV correspond to Ru x + 3p 3/2 and Ru x + 3p 1/2 , respectively. − Compared with O-RuNi@C-350, because of the electron transfer from Ni to Ru, the 3p 3/2 peaks of Ru 0 and Ru x+ in O-RuNi@C-400 negatively shifted by ∼0.81 and 0.41 eV, respectively. As shown in O 1s spectrum of O-RuNi@C-400 (Figure d), the peaks at ∼533.6, 531.9, and 530.2 eV correspond to C–O–C, CO, and Ni–O–C, respectively. , As shown in O 1s spectrum of Ni@C-400, we can see the Ni–O–C peak, but compared to O-RuNi@C-400, the Ni–O–C peak is relatively weak. It is also found that the Ni–O–C peak positively shifts as the carbonization temperature increases, while its intensity becomes stronger and then weaker.…”

“…2 eV correspond to C−O−C, C�O, and Ni−O−C, respectively 30,38. As shown in O 1s spectrum of Ni@C-400, we can see the Ni−O−C peak, but compared to O-RuNi@C-400, the Ni−O−C peak is relatively weak.…”
