“…Fourier Transform Infra-red Spectroscopy It had been reported that electropinning process of composite solutions might lead to differences in the composition of the pre-spun solution and the nanofibres deposited [12][13] . In the light of this, the infra-red spectroscopy of deposited fibres was analyzed.…”

Silver-impregnated polyacrylonitrile (PAN) nanofibre was prepared through electrospinning process. Infra-red spectroscopy (FT-IR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Thermo gravimetric analyses (TGA/DTA) were used to characterize PAN and PAN/Ag composites. The XRD results reflects decrease in the crystallinity of PAN as it is been modified with Ag. Antibacterial activity of PAN/Ag was also investigated.

One-dimensional channel materials, such as zeolites and mesoporous silicas, are very attractive hosts for the preparation and investigation of hierarchically organized structures, presenting a successive ordering from the molecular up to macroscopic scale. The focus of this article is on artificial photonic antenna systems and on photocatalytically active layers that have been built by incorporating organic dyes, complexes, metal cations and clusters into 1-D nanochannel materials. We show that zeolite L as a host material allows for the design and preparation of a large variety of highly organized hostguest systems. The combination of a tuneable host morphology and the possibility of obtaining highly organized molecular patterns of guests leads to a variety of potential optical and photoelectronic applications. Strongly absorbing systems exhibiting efficient FRET along the c-axis of the zeolite crystals are accessible by sequential inclusion of multiple types of dyes. These new light-harvesting materials offer unique possibilities as building blocks for solarenergy conversion devices. A complementary approach consists in integrating photochemically active substances into zeolite monolayers coated on an electrode and taking advantage of intrazeolite processes for designing a reversible electrode for photocatalytic water oxidation. The photoelectrochemical water splitting capability of systems based on Ag ? /AgCl/Ag n -zeolite photoanodes are discussed.

“…However, since Haruta et al discovered that nanosized gold particles loaded on TiO 2 exhibit high activity for catalytic oxidation of CO [13,14], the catalytic peformance of nanosized gold particles has been extensively studied [14]. Kamat et al and Calzaferri et al have found that photocurrents at TiO 2 [15] and AgCl electrodes [16] were improved by modification with nanosized gold particles. Au-loaded photocatalysts for the decomposition of nitrate ions [17], azo-dyes [18], and perchlorinated compound [19] have also been reported.…”

The effect of the photodeposition of gold particles onto several photocatalysts on the photocatalytic activities was studied. The photocatalytic activities of K 4 Nb 6 O 17 , Sr 2 Nb 2 O 7 , KTaO 3 NaTaO 3 , and NaTaO 3 doped with La for water splitting were improved when gold particles were deposited. The latter were nanoparticles, consistent with their surface plasmon absorption. The nanosized gold particle functioned as an efficient cocatalyst for photocatalytic water splitting by assisting H 2 evolution.
