要旨

High-throughput flame spray pyrolysis directly affords a low-loading Pt catalyst supported on cerium oxide, which is an excellent material for selective semihydrogenation of C₂H₂ at 180 °C, exhibiting nearly complete conversion of C₂H₂ (98.2%) with high selectivity towards C₂H₄ (87.1%). Pt in this catalyst is atomically dispersed within cerium oxide, and this structural feature restricts C₂H₄ adsorption as π-bonded, known to promote C₂H₄ selectivity.
