26 Ιουν 2024 · Herein, we design and construct an acidic-stable COF-based electrocatalyst by incorporating atomic Ru species into a vinyl-linked 2D COF with unique crossed π-conjugation (COF-205-Ru).
The Ru3p high-resolution spectrum exhibited two peaks at 463.7 and 485.0 eV attributed to metallic ruthenium (Ru 0 ), as indicated by Ru3p 2/3 and Ru3p 1/3 (Fig. 3d), confirming the...
10 Ιαν 2019 · In contrast to Ru nanoparticles, single Ru sites supported on N-doped porous carbon greatly promoted electroreduction of aqueous N 2 selectively to NH 3, affording an NH 3 formation rate of 3.665 m g N H 3 h − 1 m g Ru − 1 at −0.21 V versus the reversible hydrogen electrode.
1 Απρ 2023 · The Fourier transformed (FT) k 2-weighted extended X-ray absorption fine structure (EXAFS) characterization shown in Fig. 1 E suggests that Ru/PNC exhibits two fitted peaks at 1.3 and 1.6 Å, associated with Ru–N and Ru-O bonds with the respective coordination number (CN) of 4.0 and 1.0 (Fig. 1 F), along with a Ru−Ru peak at 2.4 Å with the ...
2 Ιουν 2021 · Herein, we report a highly active, selective and robust Ru SAC which was synthesized by pyrolysis of ruthenium acetylacetonate and N/C precursors at 900 °C in N 2 followed by treatment at 800 °C...
In this study we report a series of new sulfur-bridged terpyridyl ligands (1a–c) which offer enhanced flexibility due to sulfur spacers linking the pyridine rings, in addition to the ability to tune electronic properties with electron-donating (Me) and electron-withdrawing (CF 3) substituents in the 4 and 4′′-positions of the sulfur-bridged liga...
