Synthesis of Zinc Oxide (ZnO) Nanoparticle using Non-Transferred DC Thermal Plasma Method: A Morphology Review

Abstract

The increase of nanomaterial usage such as nano-ZnO application in developing countries is a type of progress that is beneficial from the engineering standpoint. Being able to control the results of nanomaterial production is crucial in this development. To control the outcome is to obtain ZnO nanomaterials properties which are suitable and in accordance to its intended application. This study focuses on the morphology of ZnO nanomaterials which are synthesized by non-transferred DC thermal plasma method. In this review, parameters of the apparatus regulating the outcomes of the synthesis is studied and analyzed to find certain guidelines that affect nanomaterial morphology. Some of the findings include the influence of non-transferred DC thermal plasma torches main variables such as gas output and power input which are involved in plasma jet production. It also finds precursor input techniques in which affects the ZnO nanomaterial production outcome. The study indicates that each production parameters on the DC thermal plasma device have different ways in affecting the morphology of the synthesized nanomaterial and it is possible to control them.
