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...
Monodisperse cobalt (Co) nanoparticles (NPs) were synthesized and stabilized against oxidation via reductive annealing at 600C. The stable Co NPs are active for catalyzing the oxygen evolution reaction (OER) in 0.1 M KOH, producing a current density of 10 mA/cm2 at an overpotential of 0.39 V (1.62 V vs. RHE, no iR-correction). Their catalysis is s...

To further enhance catalytic activity and durability of nanocatalysts for oxygen reduction reaction (ORR), we synthesized a new class of 20 nm × 2 nm ternary alloy FePtM (M = Cu, Ni) nanorods (NRs) with controlled compositions. Supported on carbon support and treated with acetic acid as well as electrochemical etching, these FePtM NRs were converte...
On July 20, 2015, Ling was expelled from the Communist Party of China,[17] and was arrested to face criminal proceedings.[18] Ling's case received significant media attention, since he was the most prominent political figure expelled from the party since criminal proceedings were initiated against former Politburo Standing Committee member Zhou Yongkang. In the party's disciplinary dossier against Ling, he was accused of "violating political discipline, violating political rules, violating organizational discipline, and violating confidentiality discipline." He was further accused of taking in large bribes, aiding in the business interests of his wife, sexual misconduct with "numerous women", and illegally obtaining party and state secrets.[19]
A simple, solvent-free, solid-state self-assembly strategy for the synthesis of alkaline-metal-oxide-doped mesoporous carbons (MCs) with tunable mesopores (~5-9 nm), high surface-areas (up to 571 m2/g) and large pore volumes (up to 0.65 cm3/g) is developed via the mechanochemical assembly between polyphenol-Ca2+/Mg2+ composites and F127 copolymers....
A kind of Ti–Fe–Ni–C compound powder was prepared by a novel precursor pyrolysis process using ferro-titanium, carbonyl nickel powder and sucrose as raw materials. The powder had a very compact structure and was uniform in particle size. The TiC–Fe36Ni composite coatings were simultaneously in-situ synthesized by Reactive Detonation-gun Spraying (RDS) using these Ti-Fe-Ni-C compound powders. The coatings presented typical morphology of thermal spraying coatings with two different areas: one was the area of TiC distribution where the round fine TiC particles (from 300nm to 1μm) were dispersed in the Fe36Ni alloy matrix; the other was the area of TiC accumulation (from 2 to 4μm). The surface hardness of the composite coating reached about 94 ± 2(HR15N).
