Investigation of the active phase in K-promoted MoS2 catalysts for methanethiol synthesis
Autor: Patricia J. Kooyman, Emiel J. M. Hensen, Nikolay Kosinov, Miao Yu, Lennart van Haandel
Publikováno v: ACS Catalysis, 10(3), 1838-1846. American Chemical Society
K-promoted MoS2 is an active catalyst for the synthesis of CH3SH, a valuable chemical intermediate, from synthesis gas (CO/H2) and H2S. The promotion of MoS2 by K increases the CO conversion rate and the CH3SH selectivity and is usually linked to the
