Iron Oxide-Based Heterogeneous Catalysts for Environmental Applications

Heterogenous catalysts based on iron are widely used in environmental remediation reactions due to their abundance and less toxicity. The prospects of upscaling and the risks of leaching during the treatment processes are important considerations to choose iron-based materials. Particularly, various forms of iron oxides, doped forms, iron oxyhydroxides in bulk and nanoforms are increasingly used for catalysis of environmental remediation. In this chapter, we have given the overview of these minerals and general variety of their usage in environmental catalysis. The applications of these iron-based materials in environmentally important reactions such as oxidation of volatile organic compounds (VOCs) and CO, selective catalytic reduction of NOx and Fenton reactionFenton reaction are described.
