Sustainable Recycling of Insoluble Rust Waste for the Synthesis of Iron-Containing Perovskite-Type Catalysts.

ABSTRACT: Insoluble rust waste from the scraping of rusted iron-containing materials represents a cheap, eco-friendly, and available source of iron. LaFeO₃ perovskite-type powders were successfully prepared by solution combustion synthesis using rust waste from an electricity transmission tower manufacturer. Solution combustion synthesis enabled introduction of this insoluble iron precursor directly into the final product, bypassing complex extraction procedures. Catalytic activity in the propylene oxidation of the waste-derived LaFeO₃ with stoichiometric Fe/La ratio was almost identical to the commercial iron nitrate-derived LaFeO₃, thus demonstrating the viability of this recycling solution. The amount of waste iron precursor was varied and its effect on the powder
