WebAbstract. In this study, the CeO 2-Fe 2 O 3 mixed oxide catalysts have been prepared by combustion method using gel-created tartaric acid. The ability of effective carbon monoxide (CO) oxidation to carbon dioxide (CO 2) by CeO 2-Fe 2 O 3 catalyst under low-temperature conditions was also demonstrated. The calcined CeO 2-Fe 2 O 3 material has a porous … WebMar 2, 2024 · INTRODUCTION Carbon monoxide (CO) is an odorless, tasteless, colorless, nonirritating gas formed by hydrocarbon combustion. The atmospheric concentration of CO is generally below 0.001 percent, but it may be higher in urban areas or enclosed environments. CO binds to hemoglobin with much greater affinity than oxygen, forming … cpu cache interface
