Chemical Science (IF: 9.063)



1. Solid-solution alloy nanoparticles of a combination of immiscible Au and Ru with a large gap of reduction potential and their enhanced oxygen evolution reaction performance

Chem. Sci., 2019, Advance Article

DOI: 10.1039/C9SC00496C



Scientists at Kyoto University, Japan, synthesised  AuxRu1−x solid-solution alloy NPs for the first time over the whole composition range using a chemical reduction method, for use as OER catalysts. This is significant, as Au and Ru have the largest gap in reduction potential among noble metals and are completely immiscible even at temperatures as high as their melting points in the bulk state. They found that the smallest amount of Au generated the highest performance.


日本京都大学的科学家们首次使用化学还原法合成了全组成范围的AuxRu1−x 固溶体合金纳米粒子,可用作氧析出反应(OER)催化剂。该工作的重要性在于Au和Ru具有贵金属之间最大的还原电位差,而且在本体状态下即使温度达到熔点两者也完全不混熔。作者发现最小量的Au产生了最高的性能。

2. Synergetic interaction between neighboring platinum and ruthenium monomers boosts CO oxidation

Chem. Sci., 2018, Advance Article

DOI: 10.1039/C9SC00658C



Researchers at Peking University used an icing-assisted photocatalytic reduction method to construct neighboring Pt-Ru monomers on an N-vacancy-rich g-C3N4 surface, and used DFT simulations to confirm that the Pt-Ru monomers are optimal in comparison to neighboring Pt-Pt/Ru-Ru monomers or isolated Ru/Pt atoms. This work demonstrates new insights for the development of these types of atomically dispersed metal catalysts for use in CO oxidation.


北京大学的研究人员使用冰助光催化还原方法在富含N空位的石墨相氮化碳(g-C3N4)表面构建了相邻的Pt-Ru单体,并使用密度泛函理论(DFT)模拟证实了Pt-Ru单体与相邻的Pt-Pt/Ru-Ru单体或分离的Ru/Pt原子相比是最佳的。这项工作为开发用于CO氧化的此类单原子分散金属催化剂提供了新见解。

Sustainable Energy & Fuels (IF pending)



1. The energetic implications of introducing lithium-ion batteries into distributed photovoltaic systems

Sustainable Energy Fuels, 2019, Advance Article

DOI: 10.1039/C9SE00127A


Batteries for stationary applications can prove to be crucial for enabling high penetration of solar energy, but production and use of batteries comes with an energetic cost. This study quantifies how adding a lithium-ion (Li-ion) battery affects the energetic performance of a typical residential photovoltaic (PV) system under a wide range of climatic conditions.
