Experimental study of dielectric barrier discharge in mixtures of carbon dioxide and oxygen

Abstract

Carbon dioxide decomposition in mixtures of CO2and O2has been experimentally investigatedusing dielectric barrier discharge, with special interest on O3and COproductions. Experiments have been conducted at different frequencies and operating voltages, and the concentration of O3and COhave been measured by means of absorption spectroscopy in the UV and in the IR regions. According to the observations, theproductionof both speciescan be substantially increased by adding molecular oxygento carbon dioxide, even in small proportions
