FCCVD yöntemi ile alüminyum folyo üzerinde dikey olarak hizalanmış karbon nanotüp büyümesinin geniş alan sentezi

Bu çalışmada, yatay bir tüp fırında FCCVD yöntemiyle 610 oC sıcaklıkta Al folyo üzerine VA-CNT’ler homojen bir şekilde sentezlenmiştir. Karbon kaynağı olarak etanol kullanılırken katalizör olarak da ferrosen kullanılmıştır. Çapları ~10-15 nm aralığında, uzunlukları ise ~30-35 µm aralığında değişen VA-CNT'ler elde edilmiştir. VA-CNT'lerin yapısal ve morfolojik analizleri, X-Işını Kırınım (XRD), Alan Emisyon Taramalı Elektron Mikroskobu (FESEM), Enerji Dağılım X-Işını Spektroskopisi (EDS), Raman Spektroskopisi ve X-Işını Fotoelektron Spektroskopisi (XPS) kullanılarak belirlenmiştir. Geniş bir alanda Al folyo üzerinde FCCVD yöntemiyle sentezlenen bu VA-CNT'ler, özellikle enerji depolama, optoelektronik ve sensör uygulamalarında kullanılabilme potansiyeline sahiptir.

Large-area synthesis of vertically aligned carbon nanotubes growth on the aluminum foil via FCCVD method

In this study, VA-CNTs were synthesized homogeneously on Al foil at 610 oC temperature by Floating Catalyst Chemical Vapor Deposition (FCCVD) method in a horizontal tube furnace. While ethanol was used as the carbon source, ferrocene was used as the catalyst. VA-CNTs with diameters in the range of ~10-15 nm and lengths in the range of ~30-35 µm were obtained. Structural and morphological analyzes of VA-CNTs were determined using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersion X-Ray Spectroscopy (EDS), Raman Spectroscopy and X-Ray Photoelectron Spectroscopy (XPS). These VA-CNTs, synthesized by the FCCVD method on an Al foil in a large area, have the potential applications to be used especially in energy storage, optoelectronic, and sensor.
