Core Insights - Ethylene is a crucial basic chemical raw material, and its purity directly affects the production of high-value-added chemicals downstream [1] - The removal of acetylene impurities is a key step in the ethylene polymerization industry, with catalytic hydrogenation being an important method for this process [1][2] - The development of high-performance, low-cost acetylene hydrogenation catalysts is significant due to the limitations of current palladium-silver (PdAg) alloy catalysts [1] Group 1 - A research team has successfully developed a bimetallic catalyst consisting of fully exposed copper clusters and ruthenium single atoms, achieving high activity and selectivity for acetylene hydrogenation [2] - The Ru1Cun/SiO2 catalyst demonstrated a 100% conversion rate of acetylene and a 97.6% selectivity for ethylene at 170°C, significantly lowering the temperature required for complete acetylene conversion [2] - The hydrogenation activity of the new catalyst reached 34.02 molC2H2/(molCu.h), which is 5.3 and 52.3 times higher than that of single metal Cu clusters and Cu single atom catalysts, respectively [2] Group 2 - The research findings were published in the Journal of the American Chemical Society (JACS) under the title "Fully Exposed Cu Clusters with Ru Single Atoms Synergy for High-Performance Acetylene Semihydrogenation" [3] - The study received support from various funding sources, including the National Natural Science Foundation and the National Key Research and Development Program [3]
