Prism-shaped cobalt carbide nanoparticles have been found to efficiently catalyze the Fischer-Tropsch to olefin (FTO) process—the conversion of syngas (CO + H2) to light olefins—with high selectivity and at relatively low temperature (Nature 2016, DOI: 10.1038/nature19786). The discovery is surprising because spherical counterparts of cobalt carbide crystallites “are of little use in this reaction, and because spherical particles of cobalt metal produce a . . .
