Permanganate Reduction by Hydrogen Peroxide: Formation of Reactive Manganese Species and Superoxide and Enhanced Micropollutant Abatement

Permanganate (MnO4-, Mn(VII)) is widely applied at the initial stage of water treatment to, e.g., abate taste and odor compounds, Mn(II) and Fe(II). However, its selectivity limits its application for micropollutant abatement. Hydrogen peroxide (H2O2), whi ...

Fine Particle Iron in Soils and Road Dust Is Modulated by Coal-Fired Power Plant Sulfur

Athanasios Nenes

Transition metal ions, such as water-soluble iron (WS-Fe), are toxic components of fine particles (PM2.5). In Atlanta, from 1998 to 2013, a previous study found that WS-Fe was the PM2.5 species most associated with adverse cardiovascular outcomes. We exami ...

The luminescence of NaxEu3+(2−x)/3MoO4 scheelites depends on the number of Eu-clusters occurring in their incommensurately modulated structure

Gervais Chapuis, Jean-Claude Bünzli, Alla Arakcheeva, Philip Pattison, Svetlana Eliseeva, Dmitry Logvinovich

Scheelite related compounds with general formula Mn(XO4)m are of interest owing to their optical properties, stability and relatively simple preparation. Eu3+-containing scheelites are considered as red emitting phosphors and the main factors affecting the ...

Carbon-Doped TiO2 and Carbon, Tungsten-Codoped TiO2 through Sol-Gel Processes in the Presence of Melamine Borate: Reflections through Photocatalysis

Ravindranathan Thampi, Michael Jon Mattle

A series of C-doped, W-doped, and C,W-codoped TiO2 samples have been prepared using modified sol-gel techniques. Reproducible inexpensive C-doping arises from the presence of melamine borate in a sol-gel mixture, whereas W-doping is from the addition of tu ...

Recent developments of molybdenum and tungsten sulfides as hydrogen evolution catalysts

Xile Hu, Daniel Andreas Merki

Recent work shows that nanoparticulate and amorphous molybdenum and tungsten sulfide materials are active catalysts for hydrogen evolution in aqueous solution. These materials hold promise for applications in clean hydrogen production technologies. In this ...

Economical and effective sulfide catalysts for dye-sensitized solar cells as counter electrodes

Ulf Anders Hagfeldt, Liang Wang

Molybdenum sulfide (MoS2) and tungsten sulfide (WS2) are proposed as counter electrode (CE) catalysts in a I3-/I- and T2/T- based dye-sensitized solar cells (DSCs) system. The I3-/I- based DSCs using MoS2 and WS2 CEs achieved power conversion efficiencies ...
