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...
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...
Though it has banned the suona from funerals, the local government has also paradoxically launched several initiatives to preserve the suona tradition. Since 2014, it has funded research and documentation of suona music, as well as an intangible cultural heritage protection plan that pairs around 15 masters with students. It also offers suona musicians performance opportunities. But according to Liu, the gigs are too few and too poorly compensated — some only pay 800 to 1,000 yuan ($120 to $150) for an eight-person band. He doesn’t believe that a state-sponsored imitation of the master-apprentice method will be able to sustain the tradition.
The controlled exfoliation of hexagonal boron nitride (h-BN) into single- or few-layered nanosheets remains a grand challenge and becomes the bottleneck to essential studies and applications of h-BN. Here, we present an efficient strategy for the scalable synthesis of few-layered h-BN nanosheets (BNNS) using a novel gas exfoliation of bulk h-BN in...
NixWO2.72 nanorods (NRs) are synthesized by a one-pot reaction of Ni(acac)2 and WCl4. In the rod structure, Ni(II) intercalates in the defective perovskite-type WO2.72 and is stabilized. The NixWO2.72 NRs show the x-dependent electrocatalysis for the oxygen evolution reaction (OER) in 0.1M KOH with Ni0.78WO2.72 being the most efficient, even outper...
Jiaozuo is noted for its blast furnaces and machine construction industries. The total GDP of the city in 2017 was 234.28 billion yuan, an increase of 7.4% over the previous year. Among them, the added value of the primary industry was 13.733 billion yuan, up 4.6%; the added value of the secondary industry was 13.841 billion yuan, up 6.7%; the added value of the tertiary industry was 81.143 billion yuan, up 9.1%. The per capita GDP reached 65,936 yuan. The three industrial structures changed from 6.4:59.3:34.3 of 2016 to 5.9:59.5:34.6.link
