ABSTRACT

Titanium dioxide (TiO2) with various morphologies has been successfully synthesized by a simple hydrothermal method at 150oC for 10 h using titanium butoxide (TBOT) as a precursor, deionized (DI) water and hydrochloric acid (HCl) on a fluorine-doped tin oxide (FTO) substrate. The influences of HCl volume on structural and morphological properties of TiO2 have been studied using x-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM), respectively. The result showed that several morphologies such as microsphere, microrods, nanorods and nanoflowers were obtained by varying the volume of hydrochloric acid. The crystallinity of titanium dioxide enhanced with the increasing of hydrochloric acid volume.

ABSTRAK

Titanium dioksida (TIO2) dengan pelbagai morfologi telah berjaya disintesis melalui kaedah hidroterma pada 150oC selama 10 jam dengan menggunakan titanium butoksida sebagai perintis, air ternyahion (DI) dan asid hidroklorik (HCl) pada substrat fluorin-terdop timah oksida (FTO). Pengaruh isi padu HCl pada sifat struktur dan morfologi TiO2 telah dikaji menggunakan pembelauan sinar-X (XRD) dan medan pelepasan mikroskop elektron pengimbas (FESEM). Hasil kajian menunjukkan beberapa morfologi seperti mikrosfera, mikrorod, nanorod dan bunga nano diperoleh dengan mengubah isi padu asid hidroklorik. Penghabluran daripada titanium dioksida dipertingkatkan dengan meningkatkan jumlah asid hidroklorik.

 

Kata kunci: Asid hidroklorik (HCl); medan pelepasan mikroskop elektron pengimbas (FESEM); pembelauan sinar-x (XRD); titanium dioksida (TiO2)
