2022年10月3日 · X-ray photoelectron spectroscopy (XPS) Quasi in situ XPS experiments were carried out on a Thermo Scientific ESCALAB Xi + XPS instrument. The spectrums of Mo 3d, C 1s, O 1s, and Pt 4f were ...

The spin-orbit splitting of Mo 3d dipole into Mo 3d 3/2 and 3d 5/2 bands is observed in the XPS spectrum, which can be well fitted by two 3d doublets in the form of Gaussian functions ...

2020年2月15日 · The obtained MoOx QDs showed efficient peroxidase-like activity with high sensitivity and specificity, which was proved by the ability to catalyze the oxidation of Diammonium 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) to give a color change.

In this study, the oxidation state of Mo in the s-MoOx film was investigated using XPS analysis. The XPS measurement focused on the Mo 3d characteristic peaks of s-MoOx as seen in Fig. 2....

2023年5月8日 · Here, an optimized MoOx layer with abundant oxygen vacancies was modified on Sn doped α-Fe2O3 film by simple spin coating and thermal reduction method to form a heterojunction with enhanced PEC performance. XPS results suggest that increased oxygen vacancy concentration in MoOx layers can be achieved by post annealing the samples in N2.

MoOx is a compound-oxide semiconductor with an indirect band gap and is also considered to be a promising candidate in potential applications of hole injection layer between Transparent...
