چکیده | ||
This article presents a method for producing silver nanoparticles through plasma at atmospheric pressure using electrochemical techniques. Initially, an electrochemical configuration is designed using atmospheric pressure plasma (a direct current (DC) source). Subsequently, silver nanoparticles were produced in an environment without a stabilizer and evaluated according to the treatment time. The results demonstrate that the plasma-based electrochemical method, in comparison to other methods, including traditional electrochemical, can increase the accuracy in the shape and structure of nanoparticles while simultaneously accelerating the synthesized processes of nanomaterials. Analysis revealed that the synthesized nanostructures range between 2 and 3 nanometers in size and exhibit rod-like shapes, among other morphologies. | ||

چکیده [English] | ||
این پژوهش به تولید نانوذرات نقره از طریق میکروپلاسما در فشار اتمسفر با استفاده از چیدمان الکتروشیمیایی- پلاسما میپردازد. در این کار ابتدا، پیکربندی الکتروشیمیایی با استفاده از میکروپلاسما در فشار اتمسفر و منبع DC طراحی شده و سپس، نانوذرات نقره در محیطی بدون پایدارکننده تولید و مورد بررسی قرار گرفتند. نتایج نشان میدهد که روش الکتروشیمیایی بر پایه میکروپلاسما نسبت به روشهای دیگر، از جمله الکتروشیمیایی سنتی، علاوه بر افزایش دقت در شکل و ساختار نانوذرات، منجر به تسریع در فرآیندهای ساخت نانومواد میشود. علاوه بر این، تجزیه و تحلیل نانو ذرات ساخته شده، نشان می دهد که با توجه به شرایط ساخت (زمان)، میتوان نانوذراتی با مورفولوژی مختلف مانند کروی و میله ای ساخت. | ||
