Ruthenium (Ru) has been theoretically considered a viable alkaline hydrogen evolution reaction electrocatalyst due to its fast water dissociation kinetics. However, its strong affinity to the...
1 Απρ 2023 · Furthermore, the generated H 2 and N 2 were collected using water drainage method with bifunctional Ru/PNC electrode in two-electrode OHzS cell at 100 mA cm −2 (Fig. 4 C), manifesting near 100 % Faraday efficiency with a perfectly stoichiometric H 2:N 2 ratio of 2:1.
1 Δεκ 2020 · Hydrogen (H 2) energy, with the advantages of high gravimetric energy density (146 kJ g −1), abundant reserves, sustainability and zero emission after combustion, is recognized as the most promising alternative to fossil fuels in future [[4], [5], [6], [7]].
2 Ιουν 2021 · Kinetic isotope effect (KIE) experiment by using D 2 to replace H 2 in the reductive amination reveals KIE value of 1.1, 1.7, and 2.1 for the Ru 1 /NC-800, Ru 1 /NC-900, and Ru 1 /NC-900-800NH 3...
25 Σεπ 2020 · Here we report the design, identification and evolution of an air-stable surface [bipy-Ru II (CO) 2 Cl 2] site that is covalently mounted onto a polyphenylene framework. Such a Ru II site was obtained by reduction of [bipy-Ru III Cl 4] − with simultaneous ligand exchange from Cl − to CO.
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).
