A demonstration to highlight the utility and ease of handling environmentally benign magnetically recoverable nanoparticle catalysts is described. The demonstration offers two powerful visuals. The first is a color change oxidation of tetramethylbenzidine by hydrogen peroxide catalyzed by Fe[subscript 3]O[subscript 4] nanoparticles. The second, and more pedagogically relevant to discussion of catalyst recycling, is the retrieval of these nanoparticles from solution with an external magnet and subsequent reuse for further rounds of catalysis. The demonstration, useful to instructors of general chemistry and green chemistry courses or animators of outreach activities, requires a modest time investment of less than 5 min, yet adds striking visual aids to discussions of catalyst recycling and reuse.
