Abstract

Boron nitride nanotubes (BNNTs) have many application areas thanks to their superior properties such as thermal and electrical insulation, resistance to oxidation, high hydrophobicity, and high hydrogen storage capacity, as well as biocompatible properties. Therefore, new synthesis methods are being searched for BNNT with increasing interest in recent years. In this study, high purity and yield BNNTs were synthesized using precursor materials and methods that were not previously tried in the literature. A chemical vapor storage (CVD) furnace was used for the synthesis, and various parameters were changed to achieve optimum conditions. The structure of the obtained BNNTs was characterized by Fourier conversion infrared spectroscopy (FTIR), Raman spectroscopy, and a UV-visible spectrophotometer. In addition, surface morphologies were illuminated using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). However, it has been observed that BNNTs obtained as a result of HR-TEM (high-resolution transmission electron microscope) analysis have a single-walled structure that is difficult to synthesize. This increases the importance and quality of synthesized BNNTs.

Özet

Bor nitrür nanotüpler (BNNT’ler) ısıl ve elektriksel yalıtkanlıkları, oksidasyona karşı dayanıklılıkları, yüksek hidrofobiteleri ve yüksek hidrojen depolama kapasiteleri gibi üstün özelliklerinin yanı sıra biyouyumlu özellikleri sayesinde birçok uygulama alanına sahiptir. Dolayısıyla BNNT için son yıllarda gittikçe artan bir ilgiyle yeni sentez yöntemleri araştırılmaktadır. Bu çalışmada, literatürde daha önce denenmemiş öncü maddeler ve yöntemle yüksek saflıkta ve verimde BNNT’ler sentezledi. Sentez için bir kimyasal buhar depolama (CVD) fırını kullanıldı ve çeşitli parametreler değiştirilerek optimum koşullar elde edildi. Elde edilen BNNT’lerin yapısı fourier dönüşümlü kızılötesi spektroskopisi (FTIR), Raman spektroskopisi ve bir UV-visible spektrofotometresi kullanılarak karakterize edildi. Ayrıca yüzey morfolojileri geçirimli elektron mikroskobu (TEM) ve taramalı elektron mikroskobu (SEM) kullanılarak aydınlatıldı. Bunla birlikte HR-TEM (yüksek çözünürlüklü geçirimli elektron mikroskobu) analiz sonuçlarına göre elde edilen BNNT’lerin, sentezlenmesi zor olan tek duvarlı (single-walled) bir yapıya sahip olduğu görülmüştür. Buda sentezlenen BNNT’lerin önemini ve kalitesini arttırmaktadır.
