Molybdenum oxide nanoparticles (NPs) with tunable plasmonic resonance in the near-infrared region display superior semiconducting features and photothermal properties, which are highly related to crystalline defective structures such as oxygen deficiencies. However, fundamental understanding on structure-function relationship between crystalline/defective properties is still unclear. To address...

High-quality large-area few-layer 1T' MoTe2 films with high homogeneity are synthesized by the controlled tellurization of MoO3 film. The Mo precursor plays a key role in determining the quality and morphology of the 1T' MoTe2 . Furthermore, the amount of Te strongly influences the phase of the MoTe2 . The growth method paves the way toward the scalable production of 1T' MoTe2 -based applications.

Control of light transmittance is important for optoelectronic devices such as smart windows and switchable photodetectors. In particular, that infrared can be used tuning thermal flows through windows. Plasmonic compound nanomaterials are suitable those because their electrochemically tunable localized surface plasmon resonance (LSPR). We combined CuS nanoplates with MoO3 nanosheets developing...

در این پژوهش فرآیند گوگردزدایی اکسیداسیونی (ODS) از مدل نفتی ppm 1000 دی‌بنزوتیوفن (DBT) با استفاده از کاتالیست MoO3/g-C3N4 مورد مطالعه قرار گرفت. H2O2 و استونیتریل به‌ترتیب به‌عنوان اکسیدکننده و استخراج‌کننده مورد استفاده قرار گرفتند. اثر بارگذاری فلز مولیبدن برروی g-C3N4 و سپس شرایط عملیاتی مربوط به فرآیند ODS شامل دما، مقدار کاتالیست، نسبت مولی H2O2/DBT و زمان واکنش با استفاده از طراحی آزمای...

In this study, a high energy planetary ball milling technique was used to synthesize nano-crystalline Mo-Cu alloys. Molybdenum trioxide (MoO3) and copper oxide (CuO) were used as the starting materials. Carbo-thermal co-reduction of mixed Mo and Cu oxides powders was done with milling followed by a heat treatment at a high temperature. Differential thermal analysis/thermogravimetric (DTA/TG) wa...

This paper focused on a simple approach for synthesis of molybdenum oxide (MoO3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. For more investigations, besides microwave heating, the obtained solutions were also treated by conventio...

Semiconducting oxides with reducible cations are ideal platforms for various functional applications in nanoelectronics and catalysts. Here we report an ultrathin monolayer alpha-MoO3 where tunable electronic properties different gas adsorbing behaviors upon introducing the oxygen vacancies (VO). The unique property of is that it contains three types atoms occupying Wyckoff sites absent other l...
