Abstract

Plasma is the forth state of matter after gas which created when energy was continuously supplied to neutral gas and charge carries were formed. Microwave plasma is one the method for hydrogen gas production which the zero-emission energy. However, the process considered costly and all the process done at low pressure condition. Thus, in this study a 2.45 GHz conventional microwave oven was used to generate plasma in air at atmospheric pressure. The effect of lengths of copper electrode on plasma generation and power output of microwave on temperature distribution at each electrode were investigated using Thermal Imaging Camera FLIR. Copper electrode with 3 cm, 6 cm and 18 cm was prepared. For the case of power output effect on temperature distribution, 17% (low), 33% (medium low) and 55% (medium) of power output mode were investigated. Plasma generation at tip of the copper electrode in air at atmospheric pressure was observed. It showed that plasma was generated at 6 cm and 18 cm length of electrode. Meanwhile, the higher the power output the higher the temperature at tip of the electrode. However, at 6 cm in length, the temperature of electrode was higher than that of 18 cm in length at the same power output mode and the stable plasma generation was observed. Thus, plasma can be generated when the lengths of electrode were at 1/2 and 3/2 of wavelength. Moreover 6 cm in length of electrode could be considered the most ideal and promising dimensions for the applications in decomposition of waste materials and synthesis of nanomaterials using microwave plasma discharge.
