In this paper, thin films of molybdenum oxysulphides which could be used as positive electrode materials in microbatteries were analyzed by XPS.Abstract:
Thin films of molybdenum oxysulphides which could be used as positive electrode materials in microbatteries were analysed by XPS. The results have shown the existence of a new environment for molybdenum with S 2 2- pairs, S 2- and O 2- ions. The evolution of these thin films MoOySz at different stages of their cycle in experimental generators has also been studied; the main elements involved in the redox processes have been characterized: molybdenum atoms with+6 formal oxidation number and disulphide pairs S 2 2-read more

Crystal Defect Engineering of Aurivillius Bi2MoO6 by Ce Doping for Increased Reactive Species Production in Photocatalysis
TL;DR: Wang et al. as discussed by the authors developed a general strategy to manufacture and mediate crystal defects in the host Bi2MoO6 lattice by varying the cerium dopant content, resulting in greatly improved visible-light-driven photocatalytic performance for the degradation of highly toxic nerve agent simulants (NAS) and organic dyes, as well as bacterial photoinactivation.

Converting CoMoO4 into CoO/MoOx for Overall Water Splitting by Hydrogenation
Xiaodong Yan,Lihong Tian,Lihong Tian,Samuel Atkins,Yan Liu,Yan Liu,James B. Murowchick,Xiaobo Chen +7 more
TL;DR: In this article, a CoO/MoOx crystalline/amorphous structure was reported as an effective bifunctional electrocatalyst for water splitting, which showed small onset overpotential of 40 and 230 mV for the HER and OER in 1.0 M KOH, respectively, and overall water splitting starting at 1.53 V with a robust stability.

Photoemission study of the electronic structure of Mo and Mo oxides
TL;DR: In this article, the XPS valence band of MoO2 can be qualitatively described using the molecular orbital model based on a distorted rutile structure with a characteristic structure around 5 eV reflecting the existence of cationic d interactions.

Analysis of molybdenum(3d) XPS spectra of supported molybdenum catalysts: an alternative approach
TL;DR: In this paper, a new interpretation of the Mo(3d) XPS spectra of reduced supported Mo catalysts is proposed, based on the assumption of a linear relation between the binding energies and the oxidation numbers of Mo states, with a slope of 0.8 eV per oxidation state.
