2025年1月1日 · Herein, we engineered a series of RuNa/γ-Al 2 O 3 materials, varying the size of ruthenium from single atoms to clusters/nanoparticles. The coordination environment and structure sensitivity of ruthenium were quantitatively investigated at atomic scale.

2024年5月5日 · In this study, we have successfully developed a novel catalyst consisting of ruthenium (Ru) nanoparticles supported on sodium titanate nanowires (Ru@NTO-NH) for the hydrogenolysis of low-density polyethylene (LDPE) into high-value long-chain alkanes under mild reaction conditions (180 °C, 1–2 MPa H 2), achieving yields of up to 91%.

2024年10月2日 · Ruthenium (Ru) has a wide range of valence states when compared with iron in the structure. Considering the electron configuration of Ru, it has only one electron in its outermost shell, which allows it to form coordination complexes with various oxidation states.

2019年5月3日 · Here we show that Na doping enhances both activity and durability in acid media. DFT reveals that whereas SrRuO 3 binds reaction intermediates too strongly, Na doping of ~0.125 leads to nearly...

2024年1月1日 · Na-Ru/Al 2 O 3 DFM and two ashes collected from the electrical precipitators of supercritical coal-fired power plants were used for experiments. It showed that fly ashes contaminated CO 2 adsorbents and active sites of DFMs, and caused successive drops in carbonates conversion and CH 4 selectivity upon cyclic ICCM reactions.

2020年3月18日 · Engineering the phase of metal nanocrystals while simultaneously attaining shape-controlled synthesis has recently emerged as a new frontier of research. Here, we use Ru as an example to evaluate...

The Ru-Na interfacial sites facilitate CO 2 migration through a deoxygenation pathway, involving carbonate dissociation, carbonyl formation, and hydrogenation. In-situ experiments and theoretical calculations show that stable carbonyl intermediates on metallic Ru nanoparticles facilitate heterolytic C–O scission and C–H bonding ...

Ruthenium, a polyvalent hard white metal, is a member of the platinum group and is in group 8 of the periodic table: Whereas all other group 8 elements have two electrons in the outermost shell, in ruthenium the outermost shell has only one electron (the final electron is in a lower shell).

2025年3月18日 · Майор Багрышев — опытный оперативник, привыкший полагаться только на себя. За годы службы он разоблачил не одного преступника, но когда руководство назначает ему в напарники молодого стажёра Соломатина, он ...
