Hydrogen is a promising alternative to fossil fuels that can reduce greenhouse gas emissions. Decoupled water electrolysis system using reversible proton storage redox mediator, where the oxygen evolution reaction and hydrogen are separated in time space, an effective approach producing with high purity, flexibility, low cost. To realize fast production such system, mediator capable of releasin...

High surface area (>170 m2 g−1) molybdenum nitride was prepared by the temperature-programmed nitridation of α-MoO3 with pure ammonia. The process optimized adjusting experimental variables: reaction temperature, heating rate, and molar flow rate physicochemical properties as-formed were characterized X-ray diffraction, N2 sorption, transmission electron microscopy, oxidation/reduction, phot...

Nanofibers have great importance in the membrane technology used hydrophobic surface filtration studies applied to water-oil separation products. This study improves upon properties of electrospun polystyrene-based nanofibers by increasing contact angles. As a result, been produced adding ZnO, MoO3, NiO, SiO2, and TiO2 additives polystyrene (PS)/dimethylformamide (DMF) polymer solution at 5% ma...

Catalytic fast co-pyrolysis of sewage sludge and sawdust was performed using Py/GC-MS for pyrolytic product upgrades. Metal oxides (NiO MoO3) ZSM-5 catalysts had been introduced into single catalytic pyrolysis. The combination NiO + MoO3 in mixed metal (MMOs) modified with under a dual-catalyst different layouts. In the pyrolysis process, specifically promoted formation phenols, ketones, furans...

Molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using DC magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°C) with flow oxygen at 200 sccm (standard Cubic centimeter per minute). The crystallographic structure of the films was obtained by means of x-ray diffraction (XRD) analysis. An atomic force micr...
