What is Identifying the Performance Descriptor in Direct Syngas Conversion to Long-Chain α-Olefins over Ruthenium-Based Catalysts Promoted by Alkali Metals about?
Fischer-Tropsch synthesis (FTS) provides a nonpetroleum route for the production of value-added α-olefins from syngas. However, regulating the product distribution to promote the formation of long-chain α-olefins while maintaining low selectivity to C1 byproducts (CO 2 and CH 4 ) remains a great challenge. Herein, a series of alkali metal-promoted Ru/SiO 2 catalysts were synthesized to investigate the effect of alkali metals and identify the performance descriptor for syngas to α-olefins. Xray absorption and photoelectron spectroscopy as well as CO diffuse reflectance infrared Fourier transformation spectra revealed that Ru's electronic structure can be tuned by the addition of alkali metal promoters. The Allen scale electronegativity deviation between the metallic Ru and the alkali metal promoter, which was identified as a performance descriptor, was correlated with the initial turnover frequency (TOF) and olefins distribution, as well as the chain growth probability. In addition, the fraction of olefin products was successfully adjusted from lower olefins (50.3%) to long-chain α-olefins (85.8%) by controlling the kinds of alkali metal promoters. Evidences from X-ray absorption sp
