Replacing noble metals in heterogeneous catalysts by low-cost substitutes has driven scientific and industrial research for more than 100 years. Cheap and ubiquitous iron is especially desirable, because it does not bear potential health risks like, for example, nickel. To purify the ethylene feed for the production of polyethylene, the semi-hydrogenation of acetylene is applied (8010† tons per annum). We identified the low-cost and environmentally benign complex metallic alloy Al13Fe4 as an active and selective semi-hydrogenation catalyst.
