Abstract

Three ball-milling methodologies were developed to synthesize bespoke multi-metallic K-doped Cu-Fe/ZnO-Al₂O₃ catalysts for the hydrogenation of carbon dioxide. The catalytic performance of the catalysts was benchmarked against their solution-based counterparts. The catalysts synthesized by ball milling are greener, showing smaller particles, with different selectivity towards oxygenate products.
