Co-Promoted MoS2 model catalyst for fundamental hydrodesulfurization studies can be synthesized from a mixed Co and Mo oxide precursor.

The hybrid structure of Ag nanowires (AgNWs) covered with graphene (Gr) shows synergetic effects on the performance of transparent conducting electrodes (TCEs). However, these effects have been mainly observed via large-scale characterization, and precise analysis at the nanoscale level remains inadequate. Here, we present the nanoscale verification and visualization of the improved chemical an...

The current environmental and industrial contexts require constant revision improvement of hydrotreating processes for obtaining cleaner (bio)fuels through the development supported transition metal sulfide (TMS) catalysts. present work proposes a surface-science approach to describe surface-dependent genesis cobalt-promoted active phase (CoMoS) on α-Al2O3 single crystals used as surrogates γ-A...

Čukaru Peki is a recently discovered porphyry- high-sulfidation Cu-Au deposit located 5km south of the mining town Bor in east Serbia. Three styles mineralization are distinguished system: type with massive sulfides (named Upper zone), porphyry Lower zone) and transition (between porphyries sulfides). This study investigates concentration distribution trace elements pyrite from these three zone...

Iron (Fe) cycling exerts strong control on the mobility and bioavailability of key nutrient phosphate (PO4) in soils sediments. Coprecipitation PO4 is known to alter structure Fe (oxyhydr)oxides (FeOx), however environmental fate PO4-bearing FeOx not well-understood. Here, with 9 mol% coprecipitated were prepared by Fe(III) hydrolysis Fe(II) oxidation presence dissolved PO4, addition pure synth...
