Greenhouse gas emissions have been a prevalent topic in many news channels across the world for the last decade.  Carbon Dioxide is a dominant greenhouse gas that has had severe effects on various aspects of the environment. The primary objective of this study is to develop an efficient catalyst to convert CO2 to value-added chemicals such as light olefins. A novel iron precursor was used to enable the formation of iron carbide, which was physically mixed with CeO2. The synthesized catalyst was tested for CO2 hydrogenation through a flow bed reactor at different temperatures using on-line Gas Chromatography (GC) analysis to determine the catalyst performance. The testing results showed promising selectivity for CO2 conversion to light olefins. Pulse CO Chemisorption, Temperature-programmed reduction (TPR), X-ray diffraction (XRD) and Thermogravimetric Analysis (TGA) were carried out with an aim to establish relationships between activity and properties. This study will help us understand the role of CeO2 and the iron precursor in the formation of iron carbide for CO2 conversion to light olefins.<br/>
