Influence of gadolinium doping on structural properties of carbon nanotubes

The paper presents an analysis of SEM, EDX, Raman scattering, and FTIR of Gadolinium-doped multi-walled carbon nanotubes obtained by hydrothermal method. The morphological characteristics of the materials were studied and their compositions were analyzed. Hydrothermal doping of MWCNs with Gd causes the formation of 3D network architecture and sharply increases the content of oxygen surface functionality. An unidentified intense broad peak for Gd-doped material at 2940 cm-1 was observed. The defect state of Gd-doped MWCNTs was studied by Raman spectroscopy

Investigation of thermal properties of gadolinium doped carbon nanotubes

Thermal properties characterizations for 10% and 15% Gd doped multi wall carbon nanotubes (MWCNTs) were investigated. TGA/DSC and TEM techniques were used for characterization. The features of mass loss characteristics for synthesized nanocomposite carbon nanomaterials were investigated. The specific heat capacities of the samples at a constant pressure increased as the temperature increased

Вплив легування гадолінієм на властивості вуглецевих нанотрубок

This article is devoted to the analysis of a carbon nanotube, a functionalized b-carboxyl group of a carbon nanotube and a gadolinium-doped carbon nanotube. Were analyzed the structure, purity, quality, and surface morphology, as well as the homogeneity (heterogeneity) of nanotubes. The analysis of a carbon nanotube were performed using a scanning electron microscope (SEM), energy dispersive analysis (EXD), X-ray diffraction analysis, Raman scattering, and IR luminescence. It was found that 10% doping with gadolinium strongly affects the physical properties of carbon nanotubes functionalized by a carboxyl group.      Анотація Стаття присвячена дослідженню властивостей вуглецевих нанотрубок, вуглецевих нанотрубок, функціоналізованих b-карбоксильною групою та вуглецевих нанотрубок, легованих гадолінієм. Вивчено структуру, чистоту, якість та морфологію поверхні, а також однорідність (гетерогенність) нанотрубок. Властивості вуглецевих нанотрубок вивчали за допомогою скануючої електронної мікроскопії (SEM), енергетично-дисперсійного аналізу (EXD), рентгенівського аналізу, раманівського розсіювання та ІЧ-люмінесценції. Було встановлено, що 10% легування гадолінієм сильно впливає на фізичні властивості вуглецевих нанотрубок, функціоналізованих карбоксильною групою. &nbsp
