▎ 摘　　要

NOVELTY - Nanocarbon-supported platinum-iron bimetallic catalyst comprises a nano-carbon as a carrier, platinum-iron species is uniformly supported on the surface of the nano-carbon carrier in the form of atomic clusters, the precious metal platinum is the active component, where the platinum content is 0.5-1 wt.%, iron is an auxiliary agent, where the iron content is 0.1-0.3 wt.%. USE - Nanocarbon-supported platinum-iron bimetallic catalyst used in the CO selective oxidation reaction under hydrogen-rich atmosphere (claimed). ADVANTAGE - The nanocarbon-supported platinum-iron bimetallic catalyst is easy to prepare ans cost-effective, exhibits excellent catalytic performance in the CO selective oxidation reaction under the hydrogen-rich atmosphere, realizes high selectivity and high conversion rate of CO at low temperature, keeps stable performance for a long time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a nanocarbon-supported platinum-iron bimetallic catalyst, involving: a. mixing chloroplatinic acid and ferric nitrate solution to obtain a metal salt solution, and supporting platinum and iron on nano-carbon support material by a co-precipitation method to obtain a nano-carbon-supported platinum-iron catalyst precursor; and b. placing the prepared nano-carbon-supported platinum-iron catalyst precursor in a quartz tube, and performing reduction treatment in a mixed atmosphere of hydrogen and helium to obtain product.
