Description
INTRODUCTION: The increasing frequency of coral reef bleaching, driven by rising ocean temperatures and elevated CO₂ levels, highlights the growing impact of climate change on marine ecosystems. It also reflects broader environmental consequences, including rising global temperatures, air pollution, and ecosystem disruption on land. These challenges underscore the need for the development of efficient catalysts to convert carbon dioxide (CO₂) into valuable chemicals.
METHOD: This study centers on synthesizing a novel, highly magnetic iron (Fe) copper (Cu) bimetallic catalyst through the mixing of Fe-Cu organometallic complexes in their liquid form at varying molar ratios (1:1, 3:1, 5:1, 10:1, 30:1, 50:1). The metals were combined in their respective ratios as liquid precursors, followed by solvent evaporation and mild thermal treatment. The novelty of this work arises from the use of Fe²⁺ organometallic complexes together with a Cu acetate solution as a precursor, removing the need for the conventional calcination step prior to catalyst evaluation. The prepared materials were pressed, sieved into 40-60 mesh particles, and loaded into quartz tubes for testing. CO₂ hydrogenation was performed in a flow-bed reactor under controlled temperature and CO₂/H₂ flow conditions, with product selectivity and catalyst activity analyzed via online gas chromatography (GC).
RESULTS: Results indicate that the Fe/Cu molar ratio of 1:10 demonstrated the highest selectivity and yield of light olefins.
DISCUSSION/CONCLUSION: These findings highlight the potential of Fe-Cu-based transition metal catalysts for efficient CO₂ conversion, offering a promising approach to sustainable greenhouse gas mitigation.
