Graphene is considered a next-generation electrode for indium tin oxide (ITO)-free organic photovoltaic devices (OPVs). However, to date, limited numbers of OPVs containing surface-modified graphene electrodes perform as well as ITO-based counterparts, and no devices containing a bare graphene electrode have been reported to yield satisfactory rectification characteristics. In this report, we p...

Single-layer MoS2-MoO3-x heterojunction nanosheets with visible-light-sensitive band gap energy and average lateral dimensions of ~70 nm were synthesized by using a two-step combined exfoliation method. The was initiated from pristine MoS2, while some sulfur sites in expanded MoS2 sheets during exfoliating substituted ambient non-thermal oxygen, resulting formation ?-MoO3-x crystalline domains....

Lignin is an attractive feedstock for low molecular weight biobased phenols using depolymerization strategies such as reductive catalytic fractionation or fast pyrolysis. Such often yield a product mixture enriched in lignin-derived monomers with methoxy substituents. Selective hydrodeoxygenation (HDO) effective methodology to demethoxylate these into valuable alkylated phenols. Here, we report...

MoO(3) nanowires synthesized using a biomolecule-assisted hydrothermal approach showed excellent adsorption ability for the removal of RhB and were also shown to be excellent pseudocapacitor materials.

In this paper, we propose for the first time synthesis of α-MoO3 nanorods in a one-step procedure at mild temperatures. By changing growth parameters, microstructure and controllable morphology resulting products can be customized. The average diameter as-prepared is about 200 nm. electrochromic capacitance properties synthesized were studied. results show that 550 nm have 67% high transmission...

In situ metal, acid and metal-acid (bifunctional) catalytic active functions were prepared following partial reduction by hydrogen of MoO3 deposited on TiO2 at temperatures between 623 K and 673 K. The bifunctional structure is obtained following the reduction of MoO3 to MoO2. The metallic properties of MoO2 are attributed to the delocalized  electrons above the Mo atoms place along the C-axis...

In industry, one of the main catalysts typically employed for the selective oxidation of methanol to formaldehyde is a multi-component oxide containing both bulk Fe2(MoO4)3 and excess MoO3. It is thought that the excess MoO3 primarily acts to replace any molybdenum lost through sublimation at elevated temperatures, therefore preventing the formation of an unselective Fe2O3 phase. With both oxid...

In situ Raman spectroscopy is rapidly becoming a very popular catalyst characterization method because Raman cells are being designed that can combine in situ molecular characterization studies with simultaneous fundamental quantitative kinetic studies. The dynamic nature of catalyst surfaces requires that both sets of information be obtained for a complete fundamental understanding of catalyti...

Fe-based catalysts doped with Mo were prepared and tested in the catalytic decomposition of methane (CDM), which aims for the co-production of CO2-free hydrogen and tubular nanostructured carbon (NC). Catalysts performance were tested in a thermobalance operating either at isothermal or temperature programmed mode by monitoring the weight changes with time or temperature, respectively, as a res...
