ABSTRACT

This paper presents facile and rapid synthesis route of Ni nanoparticles at approximately 180°C in the mixture composed of ethylene glycol (EG) with hydrazine (N2H4) as a reducing agent. X-ray diffraction (XRD) analysis revealed that Ni2+ can be reduced completely to Ni metal in 15 min. XRD analysis also indicated that the as-synthesized nanoparticles were pure Ni with face-centered cubic (fcc) crystal structure. Transmission electron microscopy (TEM) results showed that the sample with heating duration of 15 min has the most narrow size distribution and the size increased as the reaction time increased.

Keywords: Nanoparticles; nickel; polyol

ABSTRAK

Kertas ini melaporkan cara mudah dan pantas bagi menyediakan nanozarah Ni pada suhu lebih kurang 180°C dalam campuran yang terdiri daripada etilena glikol (EG) dan hidrazina sebagai agen penurunan. Analisis XRD menunjukkan Ni2+ boleh diturunkan kepada logam Ni sepenuhnya dalam masa 15 minit. Ia juga menunjukkan yang terhasil adalah Ni berstruktur kubik bermuka pusat (kbm). Keputusan TEM menunjukkan bahawa sampel yang dipanaskan dengan jangka masa 15 minit menghasilkan partikel dengan taburan saiz paling kecil dan saiz bertambah dengan penambahan masa tindak balas.

Kata kunci: Nanozarah; nikel; poliol
