Photocatalytic degradation of organic dyes with H_3PW_(12)O_(40)/TiO_2-SiO_2

Rare Metals 2016年第10期35卷 797-803页

作者： Shui-Jin Yang Yu-Lin Xu Wen-Peng Gong Yong-Kui Huang Guo-Hong Wang Yun Yang Chuan-Qi Feng Hubei Collaborative innovation center for Rare Metal Chemistry College of Chemistry and Chemical EngineeringHubei Normal University College of Chemistry and Chemical Engineering Hubei University

H3PW12O40/TiO2-SiO2 was synthesized by impregnation method which significantly improved the catalytic activity under simulated natural light. The prop- erties of the samples were characterized by Fourier trans- form infrared spectra （FTIR）, X-ray powder diffraction pattern （XRD）, Scanning electron micrographs （SEM）, and Zeta potential. Degradation of methyl violet was used as a probe reaction to explore the influencing factors on the photodegradation reaction. The results show that the opti- mal conditions are as follows： initial concentration of methyl violet of 10 mg·L^-1, pH of 3.0, catalyst dosage of 2.9 g·L^-1, and light irradiation time of 2.5 h. Under these conditions, the degradation rate of methyl violet is 95.4 %. The reaction on photodegradation for methyl violet can be expressed as the first-order kinetic model, and the possible mechanism for the photocatalysis under simulated natural light is suggested. After used continuously for five times, the catalyst keeps the inherent photocatalytic activity for degradation of dyes. The photodegradation of methyl orange, methyl red, naphthol green B, and methylene blue was also tested, and the degradation rate of dyes can reach 81%-100%.

Jointly optimized congestion control, forwarding strategy,and link scheduling in a named-data multihop wireless network

引用

Frontiers of Information Technology & Electronic Engineering 2017年第10期18卷 1573-1590页

作者： Cheng-cheng LI Ren-chao XIE Tao HUANG Yun-jie LIU State Key Laboratory of Networking and Switching Technology Beijing University of Posts and Telecommunications Beijing Advanced innovation center for Future Internet Technology Beijing University of Technology

As a promising future network architecture, named data networking(NDN) has been widely considered as a very appropriate network protocol for the multihop wireless network(MWN). In named-data MWNs, congestion control is a critical issue. Independent optimization for congestion control may cause severe performance degradation if it can not cooperate well with protocols in other layers. Cross-layer congestion control is a potential method to enhance performance. There have been many cross-layer congestion control mechanisms for MWN with Internet Protocol(IP). However, these cross-layer mechanisms for MWNs with IP are not applicable to named-data MWNs because the communication characteristics of NDN are different from those of IP. In this paper, we study the joint congestion control, forwarding strategy, and link scheduling problem for named-data MWNs. The problem is modeled as a network utility maximization(NUM) problem. Based on the approximate subgradient algorithm, we propose an algorithm called ‘jointly optimized congestion control, forwarding strategy, and link scheduling(JOCFS)'to solve the NUM problem distributively and iteratively. To the best of our knowledge, our proposal is the first cross-layer congestion control mechanism for named-data MWNs. By comparison with the existing congestion control mechanism, JOCFS can achieve a better performance in terms of network throughput, fairness, and the pending interest table(PIT) size.

A mixed organic（4-phenylbutylamine, 4-PBA） and inorganic（cesium, Cs） cations are used to deposit quasi-two-dimensional layered perovskites. This layered perovskites exhibit good film coverage as twodimensional perovskites and high emission performance close to three-dimensional organic–inorganic hybrid perovskites. Light-emitting diodes（LEDs） are fabricated by using solution process based on the quasi-two-dimensional layered perovskites. The perovskite LEDs exhibit a sky-blue emission with electroluminescence peak at 491 nm and a low turn on voltage at 2.9 V. The maximum external quantum efficiency reaches 0.015% at brightness of 186 cd/m^2.

Optimizing the fabrication of carbon nanotube electrode for effective capacitive deionization via electrophoretic deposition strategy

引用

Progress in Natural Science:Materials International 2018年第2期28卷 251-257页

作者： Simeng Zhang Yue Wang Xinyu Han Yanmeng Cai Shichang Xu Chemical Engineering Research center School of Chemical Engineering and Technology Tianjin University Tianjin Key Laboratory of Membrane Science and Desalination Technology Collaborative innovation center of Chemical Science and Engineering Tianjin

In order to obtain superior electrode performances in capacitive deionization（CDI）, the electrophoretic deposition（EPD） was introduced as a novel strategy for the fabrication of carbon nanotube（CNT） *** parameters, including the concentration of slurry components, deposition time and electric field intensity, were mainly investigated and optimized in terms of electrochemical characteristic and desalination performance of the deposited CNT electrode. The SEM image shows that the CNT material was deposited homogeneously on the current collector and a non-crack surface of the electrode was obtained. An optimal preparation condition of the deposited CNT electrode was obtained and specified as the Al（NO3）3 M concentration of 1.3 × 10;mol/L, the deposition time of 30 min and the electric field intensity of 15 V/cm. The obtained electrode performs an increasing specific mass capacitance of 33.36 F/g and specific adsorption capacity of 23.93 mg/g, which are 1.62 and 1.85 times those of the coated electrode respectively. The good performance of the deposited CNT electrode indicates the promising application of the EPD methodology in subsequent research and fabrication of the CDI electrodes for CDI process.
