Molybdenum oxide particles for dye removal and tribology

Effect of thermal oxidation on structural and tribological properties of MoS2 films

“…MoO 2 and MoO 3 phases were balanced at 350°C, and the intensity of MoO 3 phases increased at 400°C. On the other hand, while there was no change in the Fe peaks, it was observed that the MoS 2 (002) peak intensity decreased considerably due to the formation of other oxide peaks at 400°C 21 …”

“…The obtained oxide peaks especially at 400 C coincides with the peaks previously obtained in the literature. 19 When thermal oxidation temperatures were examined separately, it can be seen that there was no significant change at 250 C except for the disappearance of the MoS 2 (100) peak, a sharp increase in MoO 3 (320) phase intensity at 300 C. 20 MoO 2 and MoO 3 phases were balanced at 350 C, and the intensity of MoO 3 phases increased at 400 C. On the other hand, while there was no change in the Fe peaks, it was observed that the MoS 2 (002) peak intensity decreased considerably due to the formation of other oxide peaks at 400 C. 21 Microstructural characteristics of MoS 2 films subjected to thermal oxidation were determined by scanning electron microscope (SEM) cross-section and surface images (Figure 2). When the SEM images were examined, it was seen that the films were generally homogeneous and dense.…”

Excellent Bifunctional Water Electrolysis Activities of α-MoO3/AC Nanocomposites

“…These play a key role for promoting the oxygen-associated reaction during the electrocatalytic water splitting process [33,36]. Accordingly, many research groups have attempted to fabricate highquality α-MoO 3 by utilizing several experimental methods (e.g., microwave-assisted chemical synthesis [39], ultrasonication [40], water-based exfoliation [41], hydrothermal growth [38,42], wet chemical process [43,44], sol-gel [45][46][47], and ball milling [48]). Despite such substantial efforts, the electrocatalytic performances of α-MoO 3 are still unsatisfiable because of its small electrochemically active site, poor ionic conductivity, poor electronic conductivity, and sluggish kinetics [33,49].…”
