本文主要研究内容
作者（2019）在《Nanosheet-structured K–Co–MoS2 catalyst for the higher alcohol synthesis from syngas: Synthesis and activation》一文中研究指出：The nanosheets structured K–Co–MoS2 catalyst was prepared through a one-step hydrothermal synthesis combined with the wetness impregnation. The fresh catalyst has a high dispersion of Co–Mo–S active phase and no Co9S8 is found. The pure H2 activated catalyst shows a higher intrinsic activity, especially the C2+ OH selectivity for the higher alcohol synthesis compared to the one activated by 5% H2/N2 atmosphere. The reason is attributed to that the pure H2 activation more effectively suppresses the formation of Co9S8 and stabilizes the Co–Mo–S active phase during the reaction due to the formation of SH species.
Abstract
The nanosheets structured K–Co–MoS2 catalyst was prepared through a one-step hydrothermal synthesis combined with the wetness impregnation. The fresh catalyst has a high dispersion of Co–Mo–S active phase and no Co9S8 is found. The pure H2 activated catalyst shows a higher intrinsic activity, especially the C2+ OH selectivity for the higher alcohol synthesis compared to the one activated by 5% H2/N2 atmosphere. The reason is attributed to that the pure H2 activation more effectively suppresses the formation of Co9S8 and stabilizes the Co–Mo–S active phase during the reaction due to the formation of SH species.
