Synthesis of Hierarchical Flower-like AlOOH and TiO2/AlOOH Superstructures and their Enhanced Photocatalytic Properties

Abstract: Hierarchical flower-like boehmite superstructures (HFBS) composed of intermeshed nanoflakes were synthesized by hydrothermal treatment from as-formed aluminum hydroxide microspheres, which were prepared by adding aluminum spheres into a sodium metaaluminate solution. A two-step mechanism for the formation of HFBS is proposed, which involves initial formation of Al(OH)3 microspheres followed by their transformation to AlOOH. The as-prepared HFBS superstructures can be easily transformed into γ-Al2O3 superstructures without morphology change by calcination at 500 °C for 2 h. Furthermore, the TiO2 nanoparticles can homogeneously deposited on the surface of HFBS by the vapor-thermal method. The TiO2 nanoparticles coated on HFBS showed higher photocatalytic activity for photocatalytic decolorization of rhodamine B (RhB) aqueous solution than Degussa P25 (P25) and TiO2 powders prepared at the same experimental conditions. A significant enhancement of the photocatalytic activity can be related to several factors...

Effects of polymer-grafted natural nanocrystals on the structure and mechanical properties of poly(lactic acid): A case of cellulose whisker-graft-polycaprolactone

Abstract: In this work, polysaccharide nanocrystals—rodlike cellulose whiskers (CWs)—were surface-grafted with polycaprolactone (PCL) via microwave-assisted ring-opening polymerization, and filaceous cellulose whisker-graft-polycaprolactone (CW-g-PCL) nanoparticles were produced. Moreover, the resultant nanoparticles were incorporated into poly(lactic acid) (PLA) as a matrix, and they showed superior function for enhancing the mechanical performance of PLA-based materials in comparison with platelet-like nanoparticles of starch nanocrystal-graft-PCL. The optimal loading level of CW-g-PCL was 8 wt %, and this resulted in simultaneous enhancements of the strength and elongation of approximately 1.9- and 10.7-fold, respectively, over those of the neat PLA material. In this case, the rigid CW nanoparticles contributed to the endurance of higher stress, whereas the grafted PCL chains improved the association between the PLA matrix and the CW-g-PCL filler and hence facilitated the transfer of stress to the rigid CW nanoparticles. Furthermore, such a fully biodegradable PLA-based nanocomposite shows great potential for environmentally friendly materials because of its high mechanical performance. © 2009 Wiley Periodicals, Inc.
