Synthesis-Dependent Phase Evolution and Catalytic Behavior of Unsupported Iron Catalysts for CO2 Hydrogenation to C2-C4=
Iron-based catalysts are widely investigated for CO2 hydrogenation to light olefins due to their low cost, abundance, and ability to form oxidic and carbidic phases involved in the RWGS-FTS pathway. However, supports and promoters can obscure the intrinsic role of iron phase evolution. Here, unsupported Fe nanoparticle...
