Hybrid CoMoS - polyaniline nanowires catalysts for hydrodesulfurisation applications
نویسندگان
چکیده
Catalytic performances of promoted CoMoS catalysts were greatly improved via a synthesis strategy based on the structuration active phase using self-assembled PANI (Polyaniline) nanowires followed by an addition step cobalt acetylacetonate oxidic or sulfided Mo-based hybrids. Taking into account different promotion levels, slabs lengths determined XPS and TEM, highest rate constants normalized mol (MoS2)edges+corner in hydrodesulfurization 3-methylthiophene obtained when Co(acac)2 is deposited MoS3/PANI hybrid precursor. The HDS for samples increase Co/Moedges+corner atomic ratios whereas optimum HDS/HYD selectivity same ratio was observed.

متن کاملPolyaniline nanofibers: a unique polymer nanostructure for versatile applications.
Known for more than 150 years, polyaniline is the oldest and potentially one of the most useful conducting polymers because of its facile synthesis, environmental stability, and simple acid/base doping/dedoping chemistry. Because a nanoform of this polymer could offer new properties or enhanced performance, nanostructured polyaniline has attracted a great deal of interest during the past few ye...
