Synthesis and Characterization of Carbon Nanotubes Decorated with Gold Nanoparticles

Abstract

In presented work we report results of simple and viable method for producing Au/CNT composites. Chemical composition and crystallographic structure of the Au/CNT composites was confirmed by X-ray diffraction measurements, while transmission and scanning electron microscopy were used to characterize the morphology of nanocrystals as well as the distribution of nanocrystals in the composite. The obtained particles with relatively small diameter (less than 9 nm) were found to be spatially well dispersed on the carbon nanotubes. The density of attached Au-nanoparticles is not sufficient, and cannot be improved by simple increasing gold loading.

Poly(vinylidene fluoride) composites with carbon nanotubes decorated with metal nanoparticles

“…CNT decorated with platinum (Pt) nanoparticles were efficiently synthesized trough an organic colloidal process without aggregation [5]. The composites were suitable to the production of electrochemical sensors with high sensitivity [6]. Carbon materials loaded with faceted Pt nanocrystals [7] exhibited exceptional activity and recyclability for asymmetric hydrogenation of α-ketoesters, similarly to Pt nanoparticles/CNT composites efficiently used for asymmetric heterogeneous hydrogenation of methyl pyruvate with highest enantioselectivity [8].…”

Ag/Au Alloy LSPR Engineering by Co‐deposition of RF‐Sputtering and RF‐PECVD

“…Ag/DLC, Au/DLC and Ag‐Au/DLC, we synthesized the samples with the similar condition of 2.4 Pa and 100 W in 1 min. Figure shows the XRD pattern of these samples which indicates the formation of Ag, Au and Ag‐Au/DLC as FCC structure . The average size of samples is estimated by Debye‐Scherrer equation; …”

Benzilamin İnce Filmleri İle Kovalent Bir Şekilde Modifiye Edilmiş Silisyum Yüzeyleri Üzerinde Sitrat-Kaplı Altın Nanopartiküllerin Üretimi ve Karakterizasyonu

“…Organik filmlerle kimyasal yada elektrokimyasal olarak modifiye edilmiş yüzeyler, elektronik ve fotonik aygıtlarda moleküler komponent olarak potansiyel uygulama alanı bulmaları nedeniyle yakın zamanlarda oldukça cazip materyaller olmuşlardır. Diğer yandan metal nanopartiküller; eşsiz elektriksel, optiksel ve manyetiksel özelliklerinden dolayı; elektrik, optik ve manyetik malzeme uygulamalarında ilgi odağı haline gelmişlerdir [1,2]. Böylesine geniş uygulama alanlarına sahip ve ilginç özellikler sergileyen bu iki önemli yapının ortak bir noktada birleştirilmesi, yeni materyalleri üretmek için şüphesiz büyük bir katkı sağlayacaktır.…”
