Abstract
Non-thermal microplasmas are gaining attention of research community due to their unique physical, chemical, optical and catalytic properties. Due to theses remarkable properties, microplasmas are being used in medicine, electronics, material processing and biotechnology. In this study, silver nanorods (AgNRs) were synthesized by coupling dc plasma with aqueous solution of silver nitrate (AgNO3). Sucrose was added in the solution as a stabilizing agent. AgNRs were produced in aqueous solution by reducing AgNO3 with dc plasma jet of argon at atmospheric pressure. No additional reducing agent was added used during production of AgNRs. Different molar ratios of AgNO3 were used to control the size and dispersion of nanorods. Chemical composition and surface morphology of AgNRs were examined by using different techniques, such as scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The EDX spectrum confirmed that nanorods are AgNRs metallic silver with atomic weight of 16.86%. SEM micrographs revealed the formation of AgNRs. The rod length varied from 5 nm to 100 nm, depending on the molarity of solute.
