Effect of sulfidation temperature on the intrinsic activity of Co–MoS2 and Co–WS2 hydrodesulfurization catalysts

Analysis of electron beam damage of exfoliated MoS2 sheets and quantitative HAADF-STEM imaging

“…Sulfide semiconductors, including copper-containing sulfide materials have remarkable applications in photovoltaic conversion [8-10]. Metal dichalcogenides (MX 2 ) have increased relevantly their importance in applications as semiconductor materials focused in the high charge carrier mobility [11-12], besides the catalytic and lubricant applications and other interesting properties [13-14]. MoS 2 monolayer is a direct band-gap semiconductor unlike its bulk nature at 1.2 eV [15], as a consequence a remarkable increase in luminescence is experimentally measured [16].…”

Fe3O4 Nanoparticles-Supported Palladium-Bipyridine Complex: Effective Catalyst for Suzuki Coupling Reaction

“…Additionally, as MNPs have a high surface area, MNPs-supported catalysts also show high dispersion and reactivity with a high degree of chemical stability. The various types of organic reactions using the MNPs-supported catalysts that have emerged recently include C-C coupling reactions [17][18][19][20][21][22][23][24], hydroformylation [25,26], hydrogenation [27][28][29][30][31][32][33][34][35], C-N coupling reaction [36,37], oxidation [38][39][40][41][42][43], cleavage of allyl esters and ethers (deallylation catalyst) [44], enantioselective acylation [45], multicomponents Aza-Sakurai reaction [46], the Paal-Knorr reaction [47], CO 2 cycloaddition reactions [48], asymmetric hydrosilylation of ketones [49], and esterification [50]. Other reports of MNPs-supported catalysts include O-Alkylation reaction [51], halogen exchange reaction [52], polymerization reactions [53], enzymes for carboxylate resolution [54], amino acids for ester hydrolysis [55], organic amine catalysts promoting Knoevenagel [56], one-pot reaction cascades [57], and the various acidcatalyzed reactions (deprotection reaction of benzaldehyde ...…”

Synthetic Fabrication of Nanoscale MoS2-Based Transition Metal Sulfides

“…The intrinsic activity of Co–Mo–S is correlated with the Co–S–Co antiferromagnetic interaction strength [94]. And the formation of dinuclear Co sulfide clusters on Mo(W)S 2 edges regardless of the coverage of Co has been confirmed by the Co K-edge EXAFS analysis.…”
