Tailoring the atomic structural configuration at metal and oxide interface offers an effective route for the development of catalysts with optimized properties. Here, we report the design of a unique structural configuration of yolk-shell-like FePt-FeOx nanoparticles (NPs), that exhibits notably enhanced activity and stability towards CO oxidation...
In this communication, we report a facile approach to constructing catalytic active hierarchical interfaces in 1-dimensional (1D) nanostructure, exemplified by the synthesis of TiO2-supported PtFe-FeOx nanowires (NWs). The hierarchical interface, constituting of atomic level interactions between PtFe and FeOx within each NW and the interactions bet...
Pt alloy nanowires (NWs) were synthesized and applied as catalysts in the title reaction. The specific activity and mass activity of 2.5 nm wide FePt NWs were higher than of a commercial Pt catalyst. The stability of FePt NWs was tested by scanning the potential in an O(2) -saturated HClO(4) solution. The corresponding polarization curves before an...
Stabilizing transition metals (M) in MPt alloy under acidic conditions is challenging, yet crucial to boost Pt catalysis toward oxygen reduction reaction (ORR). We synthesized ∼9 nm hard-magnet core/shell L10-CoPt/Pt nanoparticles with 2–3 atomic layers of strained Pt shell for ORR. At 60°C in acid, the hard-magnet L10-CoPt better stabilizes Co (5%...
After Wang took over his grandfather’s band in 2007, he felt immense pressure to sustain the reputation and tradition he had inherited, but prospective clients kept asking for new instruments and styles of music. Eventually, Wang caved, learning the electric keyboard and trumpet and recruiting an opera singer. But work continued to dry up, and Wang now often plays with other bands that have navigated the market more shrewdly.
Ling began his career as a functionary in regional branches of the Communist Youth League in his native Shanxi Province. His Youth League involvement propelled him to the national-level organization in 1979. At the Youth League Ling worked in its propaganda department and edited its flagship newspaper. Closely following the footsteps of his patron Hu Jintao, Ling was promoted to a leadership position in the General Office of the Communist Party of China in 1999, and became an important member of the State Commission for Public Sector Reform.
The recent reforms are not the first time the suona has been subject to the twists and turns of public policy. In the early days after the Communist victory in 1949, Wang’s family band played the suona not only at weddings and funerals but also at state ceremonies for sending recruits off to military service or starting construction on reservoir projects. Suona music was the soundtrack to every important moment. But during the Great Chinese Famine, no one could afford to hire musicians, and the suona was later blacklisted as part of Cultural Revolution campaigns against Confucian heritage. It wasn’t until the reform and opening-up era in the ’80s that the suona was restored to its central role in northeastern culture.
Jiaozuo (Chinese: 焦作; pinyin: Jiāozuò [tɕjáu.tswô]; postal: Tsiaotso) is a prefecture-level city in northern Henan province, China. Sitting on the northern bank of the Yellow River, it borders the provincial capital of Zhengzhou to the south, Xinxiang to the east, Jiyuan to the west, Luoyang to the southwest, and the province of Shanxi to the north.Jiaozuo is one of the core cities of the Central Plains urban agglomeration and a regional central city in the Jin-Yu border area.link
Taming interfacial electronic effects on Pt nanoparticles modulated by their concomitants has emerged as an intriguing approach to optimize Pt catalytic performance. Here, we report Pt nanoparticles assembled on vacancy-abundant hexagonal boron nitride nanosheets and their use as a model catalyst to embrace an interfacial electronic effect on Pt in...
