Bioleaching of Molybdenum from a Coal Liquefaction Catalyst Residue
bioleaching, molybdenum disulfide, catalyst residue Molybdenum disulfide, MoSz, is used as a catalyst in coal-oil coprocessing. For most processes using molybdenum catalysts to be economical, the molybdenum must be recovered and recycled. Chemical recovery schemes have been devised, but typically recover only a fraction of the molybdenum. There are reports in the literature that bacteria can ox...
متن کاملLignin-assisted exfoliation of molybdenum disulfide in aqueous media and its application in lithium ion batteries.
In this article, alkali lignin (AL)-assisted direct exfoliation of MoS2 mineral into single-layer and few-layer nanosheets in water is reported for the first time. Under optimized conditions, the concentration of MoS2 nanosheets in the obtained dispersion can be as high as 1.75 ± 0.08 mg mL(-1), which is much higher than the typical reported concentrations (<1.0 mg mL(-1)) using synthetic polym...
متن کاملThree-dimensional Nitrogen-Doped Graphene Supported Molybdenum Disulfide Nanoparticles as an Advanced Catalyst for Hydrogen Evolution Reaction
An efficient three-dimensional (3D) hybrid material of nitrogen-doped graphene sheets (N-RGO) supporting molybdenum disulfide (MoS(2)) nanoparticles with high-performance electrocatalytic activity for hydrogen evolution reaction (HER) is fabricated by using a facile hydrothermal route. Comprehensive microscopic and spectroscopic characterizations confirm the resulting hybrid material possesses ...
متن کاملMolybdenum disulfide/pyrolytic carbon hybrid electrodes for scalable hydrogen evolution.
The electrochemical generation of hydrogen fuel via the proton reduction in the Hydrogen Evolution Reaction (HER) in aqueous media is currently dependent on the use expensive noble metal catalysts for which alternatives must be sought. Molybdenum disulfide (MoS₂) has shown great promise as a suitable electrocatalyst in this regard. While many lab-scale experiments on the HER activity of this ma...
متن کاملPreparation of a Novel Super Active Fischer-Tropsch Cobalt Catalyst Supported on Carbon Nanotubes
The potential of carbon nanotubes (CNT) supported cobalt catalysts for Fischer-Tropsch (FT) reaction is shown. Using the wet impregnation method cobalt on carbon nanotubes catalysts were prepared with cobalt loading varying from 15 to 45 wt. %. The catalysts are characterized by different methods including: BET physisorption, X-ray diffraction, hydrogen chemisorption, and temperature-progra...
