- Abstract:
- ... Colloidal MnO2 is the most reactive phase of Mn(IV) while HSO3⁻ is a common reductant in water treatment. This study shows that the presence of HSO3⁻ resulted in significant increase in the decomposition rate of organic contaminants by colloidal MnO2. The degradation rate of contaminants in the MnO2/HSO3⁻ process dropped with elevating pH and a proper MnO2/HSO3- molar ratio was critical for effici ...

- Abstract:
- ... Volatile organic compounds (VOCs) are responsible for environmental problems and may affect human health. Several treatment technologies minimize VOCs emissions; among those, catalytic oxidation appears as a promising alternative. In this study, a pilot-scale catalytic reactor was developed and the influence of process parameters on toluene degradation were investigated. Inlet gases were heated by ...

Based on Volcano plotting, the controlled combination of weak and strong bond strengths of a bimetallic catalyst has the potential to maximize the catalytic effect via the formation of intermediate bond strength between the reactant and the two different types of active sites. In this study, a rational design approach was adopted to couple MoO3 and CeO2 to maximize the catalytic oxidation of Hg0 u ...

Results revealed that α-Fe(Fe2+)OOH is a nano magnetic material with goethite (α-FeOOH) -type structures and has fewer Lewis acid of Fe3+ on its surface. Moreover, α-Fe(Fe2+)OOH was effective in catalytic ozonation of 4-chloronitrobenzene (4-CNB), which is a probe contaminant that cannot be ef ...
