Characterization and mechanism of MoS2/CdS composite photocatalyst used for hydrogen production from water splitting under visible light

Enhanced photoelectrochemical and photocatalytic activities of CdS nanowires by surface modification with MoS2 nanosheets

“…The higher binding energy (Fig. 4b) [36]. When photogenerated electron of CdS is easily transferred to MoS 2 , the recombination probability of electron and hole pairs is decreased.…”

Understanding the Intrinsic Water Wettability of Molybdenum Disulfide (MoS2)

“…Data shown in Figure S1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 indicates that the sample is pure MoS2 and no additional peaks were discerned. 46,47,48 Fitting the survey spectrum for Mo 3d and S 2p peaks indicated that the results were nearly stoichiometric with atomic percentages of 37.4% and 62.6%, respectively. The difference from stoichiometry may be due to defects (e.g., point defects, ridges, step edges) on the MoS2 surface and attenuation of sulfur atoms by molybdenum atoms.…”

Understanding the intrinsic water wettability of graphite

“…Data shown in Figure S1 of Reference 70 indicates that the sample is pure MoS 2 and no additional peaks were discerned. [315][316][317] Fitting the survey spectrum for Mo 3d and S 2p peaks indicated that the results were nearly stoichiometric with atomic percentages of 37.4% and 62.6%, respectively. The difference from stoichiometry may be due to defects (e.g., point defects, ridges, step edges) on the MoS 2 surface and Assuming the same contaminants are adsorbed onto both MoS 2 and HOPG, it can be possible to elucidate qualitative information on the type of contaminants based on their size (~0.50 nm) and affinity for the fresh substrate (adsorption occurs faster on HOPG).…”
