“…Recently, much attention has been directed to the development of nanocomposites based on organic-inorganic hybrid materials, such as SiO 2 (Pinto et al 2008), CaCO 3 (Vilela et al 2010), NbOPO 4 ·nH 2 O (Pereira et al 2010,), Nb 2 O 5 (Maschio et al 2012), MgO (Maliyekkal et al 2010), silica (Xie et al 2009), TiO 2 (Daoud et al 2005), Al 2 O 3 (Alfaya and Gushikem 1999), ZrO 2 (Mulinari and Da Silva 2008), Cel/Sb 2 O 3 (Toledo et al 2000), and other applications such as membranes (Biron et al 2012), because these materials normally have improved mechanical, optical, and thermal properties due to the combination of inorganic and organic components.…”

Chemical Modification of Palm Fibres Surface with Zirconium Oxychloride

2013

Chemical modification of natural fibres has been carried out using different methods for such purposes as reinforcement in polymer matrices and heavy metals adsorption. In this work, palm fibres were modified by zirconium oxychloride in situ. The palm fibres that had been chemically modified were compared to those in nature using fibres that passed through 20 and 40 mesh screens to evaluate the influence of particle size on modification. Palm fibres were modified with ZrO 2 .nH 2 O nanoparticles through the use of zirconium oxychloride in an acidic medium in the presence of palm fibres using ammonium solution (1:3) as the precipitating agent. Scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectrophotometry (FTIR), and atomic emission spectrometry with inductively coupled plasma (ICP-AES) were used to characterize the hybrid materials. Results indicated that the particle size of the palm fibres influenced in the modification, because the fibres with smaller particle size had a greater deposition of inorganic material. The ICP technique revealed an increase of 21% nanoparticles ZrO 2 .nH 2 O deposited on fibres (40 mesh) when compared to fibres (20 mesh). The diameter of nanoparticles ZrO 2 .nH 2 O deposited on fibres was about 50 to 220 nm, as observed by SEM.

“…In the last few years, several research works were developed on the preparation of cellulose/oxide hybrid materials of the Cel/M x O y (M ¼ Ti, Zr, Nb, Sb, and Al) kind, [1][2][3][4][5][6][7] in fiber and membrane forms, and then used in diverse applications, among these the adsorption of phosphate, metallic ions such as Cu 2þ , Zn 2þ , Fe 3þ , and Cr 6þ . However, the fiber used in these research works was cellulose microfiber, a highly processed and expensive product.…”

A new material of cotton fiber/Al 2 O 3 / SiPy þ Cl À , COTALPy, was prepared containing on its surface the polymer silsesquioxane 3-n-propylpyridinium chloride strongly adhered. This new composite based on long fibers of natural cotton is chemically stable and had its adsorption properties studied. The COTALPy presented a maximum ionic exchange capacity of 0.85 mmol g À1 by potentiometric titulation. The adsorption isotherms of CuCl 2 , ZnCl 2 , CdCl 2 , NiCl 2 , and FeCl 2 in ethanol solutions were determined for each metal. The adsorption process was studied and data compared with the Langmuir model. The maximum adsorption capacities (in mmol g

“…Antimony trioxide (Sb 2 O 3 ) is a semiconducting material and possesses excellent catalytic performance in photochemistry and superior chemical stability in flame retardance [1,2]. So far, much attention has been focused on the synthesis of Sb 2 O 3 films, and the exploration of their novel properties [3,4]. By comparison, low-dimensional Sb 2 O 3 , such as nanoparticles, nanowires, nanotubes, and nanoribbons, can be expected to exhibit special properties.…”

Sb2O3nanoparticles, nanowires, and nanoribbons have been selectively synthesized in a controlled manner under mild conditions by using CTAB as a soft template. By adoptingSb(OH)4−as an inorganic precursor and the concentration of CTAB as an adjusting parameter, morphologies ofSb2O3nanostructures can be selectively controlled. Typically,CCTAB<0.15mmol favors the formation of nanoparticles (product one or short form P1); when the concentration of CATB is in the range 0.15–2.0 mmol, nanowires (P2) dominate the products; nanoribbons (P3) form above the concentration of 2.0 mmol, and when the concentration of CTAB goes further higher, treelike bundles of nanoribbons could be achieved. The method in the present study has potential advantages of easy handling, relatively low-cost, and large-scale production. The facile and large-scale synthesis of variedSb2O3nanostructures is believed to be useful for the application of catalysis and flame retardance.
