2025年2月18日 · Within this newly constructed system, the [Ru (bpy) 2] 2+ component and Cu site serve as photosensitive and catalytic active centers for photocarrier generation and H 2 O 2 production, respectively, and their integration significantly reduces the barriers to charge transfer.

2022年7月1日 · Here we report an electrochemical lithium intercalation method to improve both the activity and stability of RuO 2 for acidic oxygen evolution reaction. The lithium intercalates into the lattice...

2025年3月4日 · d The Ru K-edge XANES spectra of RuCu DAs/NGA and the references (Ru foil, Ru SAs/NGA, and RuO 2). e Ru K-edge FT k 3-weighted EXAFS spectra of RuCu DAs/NGA and references.

22 小时之前 · The potential role of asymmetric RE-O-Ru units with bridged Ov is also observed in other RE-doped RuO2 systems (e.g., Nd and Lu), where all catalysts exhibit enhanced deprotonation of oxygenated intermediates. We believe that the RE-mediated strategy presented in this work provides a new pathway for designing highly active and stable noble ...

5 天之前 · The RuO2-based catalyst (Cr0.31Ru0.69O2) showed optimal stability at a Cr/Ru ratio of 0.31/0.69 (Cr content similar to theoretical prediction), and was operated stably for over 1400 hours at a 10 mA cm-2 current density with almost no degradation.

2025年1月11日 · To maximize the overall catalytic performance, both the N-formylation of amine with CO 2 (i.e., first step) and the subsequent amide hydrogenation (i.e., second step) are required to be...

2025年1月31日 · As a proof of concept, a well-defined multi-site photocatalyst, Ru nanoparticles and Cu single atoms decorated CeO 2 nanorods (Ru-Cu/CeO 2), is developed for efficient urea production.

2025年2月21日 · To this end, a ruthenium (Ru) single atoms and sulfur (S) anions dual-doped NiFe layered double hydroxides (Ru-S-NiFe LDH) catalyst is reported with remarkably low alkaline oxygen evolution reaction (OER) overpotentials, high mass activities and prolonged stabilities at high current densities.

2025年1月15日 · In this study, rapid heating of ruthenium (III) acetylacetonate by magnetic induction heating (MIH) leads to the one-step production of Ru-RuO₂/C nanocomposites composed of closely integrated Ru and RuO₂ nanoparticles.

2024年12月1日 · Ru SA -Ru NC /TiO 2-x, a novel catalyst featuring ultrafine Ru clusters and single atoms confined within the TiO 2-x lattice, is first developed. Ru SA -Ru NC /TiO 2-x exhibits bifunctional activity toward HOR and HER in a wide potential range. High-density Ru-Ti interfacial bonds are shown to markedly boost the HOR/HER performance.
