A novel Co^Ⅱ-Fenton-like heterogeneous catalyst,(H3O)2[Co^Ⅱ(phen)(H2O)2]2[Mo^Ⅵ5O15(PO4)2]·4H2O (phen=1,10-phenanthroline,C12N2H8)(1),is synthesized and utilized for photocatalytic degradation of organic dyes and antibiotic in a wide range of *** experimental results show that 1 acting as the Fenton-like catalyst with H2O2 exhibits remarkable activity at pH 3–9 under vis-light irradiation and is merited with excellent recyclability and reusability.A variety of analytical methods,including in-situ electron paramagnetic resonance (EPR) spectroscopy and density functional theory (DFT) calculations,are applied to study the mechanism on generation of·OH and O2^·-radicals for photocatalytic *** suggests that,unlike the classical Fenton process involving the redox transformation of the central cations,the generation of·OH and O2^·-radicals is associated with the substitution of the coordinating water molecules at Co(Ⅱ) by H2O2 and/or OOH^-,followed by the light-driven O–O bond cleavage and *** outcomes of this study are striking which overcome the obstacles in the classical Fe^Ⅱ-Fenton process,including the slow redox transformation between Fe(Ⅱ) and Fe(Ⅲ) and the production of massive iron precipitates especially at elevated *** opens up new avenues for the development of the high-performance Fenton(-like) catalysts for photocatalytic degradation over extended pH and provides new insight into the related process.

High Quality A1N with a Thin Interlayer Grown on a Sapphire Substrate by Plasma-Assisted Molecular Beam Epitaxy

引用

Chinese Physics Letters 2010年第6期27卷 233-236页

作者： REN Fan HAO zhi-biao ZHANG Chen hu Jian-Nan LUO Yi Tsinghua National Laboratory for Information Science and Technology State Key Laboratory on Integrated Optoelectronics and Department of Electronic Engineering Tsinghua University Beijing 100084

We report an AIN epi-layer grown on sapphire by plasma-assisted molecular beam epitaxy with a thin interlayer structure. The effects of growth mode on threading dislocations （TDs） and surface morphology are studied. Then an interlayer structure grown under a V/Ⅲ ratio of 1 is adopted to improve the AIN crystalline quality. By optimizing the thickness of the interlayer, the TD density and surface roughness can be reduced simultaneously.

Transactions of Nonferrous Metals Society of China 2015年第12期25卷 4054-4062页

作者：张水蓉胡志彪刘开宇刘艳珍何方谢清亮中南大学化学化工学院长沙410083 龙岩学院化学与材料学院龙岩364012

A promising Co3O4/Cu O composite electrode material was successfully synthesized through a facile hydrothermal and calcination process. Effects of the surfactants hexadecyltrimethyl ammonium bromide（CTAB） and polyvinylpyrrolidone（PVP） on the morphology and electrochemical performance of the composite were investigated. Powder X-ray diffraction（XRD）, scanning electron microscopy（SEM）, transmission electron microscopy（TEM） and nitrogen adsorption-desorption experiment were employed to characterize the microstructures and morphologies of the composite. Meanwhile, the electrochemical performances of the samples were studied using cyclic voltammetry（CV）, galvanostatic charge-discharge test and electrochemical impedance spectroscopy（EIS）. The results show that the porous Co3O4/Cu O-CTAB nanoplates own the best performance and exhibits a high specific capacitance of 398 F/g at 1 A/g with almost 100% capacitance retention over 2000 cycles, and it retains 90% of capacitance at 10 A/g.

The influence of Nb-V microalloying on the hot deformation behavior and microstructures of medium Mn steel(MMS)was investigated by uniaxial hot compression *** establishing the constitutive equations for simulating the measured flow curves,we successfully constructed deformation activation energy(Q)maps and processing maps for identifying the region of flow *** concluded the following consequences of Nb-V alloying for MMS.(i)The critical strain increases and the increment diminishes with the increasing deformation temperature,suggesting that NbC precipitates more efficiently retard dynamic recrystallization(DRX)in MMS compared with solute Nb.(ii)The deformation activation energy of MMS is significantly increased and even higher than that of some reported high Mn steels,suggesting that its ability to retard DRX is greater than that of the high Mn content.(iii)The hot workability of MMS is improved by narrowing the hot processing window for the unstable flow stress,in which fine recrystallized and coarse unrecrystallized grains are present.
