It is essential to prepare highly-efficiency reproducible adsorbent for purifying industrial dye wastewater. In this work, biscuit with a layered porous structure as a template is applied to prepare a photocatalytic recyclable adsorbent of BiFeO3/Carbon nanocomposites for purifying simulative industrial dye wastewater. It is found that the structure of the prepared BiFeO3/Carbon nanocomposite is related to the natural structure of the biscuit, annealing temperatures and immersing times, demonstrated by XRD, TEM, UV-Vis and adsorptive activities. Kinetics data shows that the adsorption rate of the adsorbent to the dye is rapid and fitted well with the pseudo-second-order model, that more than 80% of dyes can be removed in the beginning 30 min. The adsorption isotherm can be perfectly described by the Langmuir model as well. It can be seen from the adsorption data that the adsorption performance can reach over 90% at pH ? 2–12, which can imply its universal utilization. The prepared BiFeO_3/Carbon nanocomposites have also displayed excellent capacities(over 90% within 30 min) for adsorption of seven different dyes and their mixed one. According to the five times photocatalytic reproducible experiments, it is proved that BiFeO_3/Carbon nanocomposites show the excellent stability and reproduction for purifying simulative industrial dyes, even the sample have been placed for one year. These research results indicate that the adsorbent BiFeO_3/Carbon can be a suitable material used in treating industrial dye wastewater potentially.

Effect of Co-polyester antistatic agent modified by carbon nanotubes on the properties of polypropylene fibers

Journal of University of Science and Technology Beijing 2007年第6期14卷 573-579页

作者： Chensha Li binsong wang Weizhe Lu Dazhi wang Zhi Li Zechao Di Ji Liang Department of Mechanical Engineering Tsinghua University Beijing 100084 China School of Chemistry and Materials Science Heilongjiang University Harbin 150080 China

Antistatic polymer fibers were investigated by using carbon nanotubes （CNTs） to enhance the antistatic ability of inner antistatic agents based on the mechanism of attracting moisture by polar radical groups. It is indicated that the antistatic ability of the fibers filled with composite antistatic agents that contain CNTs and organic antistatic agents was superior to that of the fibers filled either with pure organic antistatic agents or pure CNTs. The antistatic ability of the composite antistatic agent fabricated by an in situ process was superior to that of the composite antistatic agent fabricated by direct dispersing CNTs in the antistatic agent carrier. Moreover, the heat-treated CNTs could further enhance the antistatic effect compared with the initial CNTs. The antistatic effect is significantly influenced by the content of CNTs in the composite antistatic agent.

Increasing the charge separation and the utilization efficiency of sunlight are essential factors in a photocatalytic *** this study,we prepared crystalline N-CQDs@W_(18) O_(49) heterostructures,through the in situ growth of W_(18) O_(49) nanocrystals on nitrogen-doped carbon quantum dots(N-CQDs).N-CQDs@W_(18) O_(49) nanocomposites showed high activity in the photodegradation of ciprofloxacin(CIP)and methyl orange(MO).The photodegradation activity of the optimized N-CQDs@W_(18) O_(49)-5 sample was four times higher than that of W_(18) O_(49) under ultraviolet-visible(UV–vis) light *** photodegradation activity of N-CQDs@W_(18) O_(49)-5 sample was two times higher than that of W_(18) O_(49) under near-infrared(NIR) light *** enhanced photosensitivity of the nanocomposites was attributed to the promotion of charge separation by N-CQDs and the local surface plasmon resonance(LSPR) effect of W_(18) O_(49) under NIR light *** work provides a promising approach for designing and manufacturing photocatalysts with full-spectral responsiveness and improved charge separation.

A new candidate for photocatalytic degradating organic dyes,CdS carried by car-bon nanotubes(CdS/CNTs) ,is reported. The degradation ratio curves of methyl orange in water phase show that the capability for degradating organic molecules of CdS/CNTs is obviously higher than that of separated CdS. The degradation ca-pability enhances as the increase of the amount of net CdS catalyst,the ratio of carbon nanotubes to CdS,and the area of the template,and is influenced by the pH value and the temperature of aqueous solution. These results suggest that the photocatalyst of CdS/CNTs is very suitable for potential applications in organic waste removal from water.

We reported a nano-Ag/liquid crystalline elastomer（LCE） nanocomposite by incorporating silver nanopar- ticles into a monodomain polysiloxane-based LCE matrix via a novel experimental protocol. The photo-thermo- mechanical actuation of the LCE matrix was realized via the surface plasmon resonance of silver nanoparticles while converting light into heat. The photoresponsive properties of nano-Ag/LCE nanocomposites were investigated with varying ilhunination intensities and silver nanoparticle doping concentrations（0.04% to 0.2%, mass fraction）. The nano-Ag/LCE nanocomposites show sensitive deformation under irradiation due to their excellent photothermal con- version efficiency, and this photostimulated muscle-like actuation is fully reversible via the on-off behavior of light. Incorporating silver nanoparticles into the LCE matrix also improves the mechanical properties and enhances the load-actuation capability of the material.
