Oxidation of dichloromethane over Pt, Pd and Au supported TiO2-ZrO2, TiO2-CeO2 and TiO2 catalysts

Popis výsledku v původním jazyce

Dichloromethane (DCM) is a colorless organic liquid that possesses a moderately sweet odor, evaporates easily, but does not burn easily. While it is poorly soluble in water, it is well-miscible with many organic solvents1). DCM belongs to the group of chlorinated volatile organic compounds (CVOCs) with low molecular weight and among three most commonly used chlorinated solvents in Europe2). DCM is a part of emissions from industrial processes, mainly from the production of pharmaceutics. It is used as a paint stripper/remover or in the manufacture of photographic films, as a part of certain aerosol and pesticide products. It was evidenced that DCM is mutagenic to human cells and since 2017 it is included in 2A Group (probable carcinogens to humans) according to International Agency for Research on Cancer. With respect to negative health effects of most CVOCs, more stringent regulations of their emissions all over the world are set3). Compared to VOCs abatement, the CVOCs abatement is much more difficult to carry out. Higher temperatures (above 450oC) are usually required for total CVOCs oxidation in industrial technological units. Since the catalytic oxidation/combustion serves as a cost-efficient, environmentally and in industrial scale proven technology for CVOCs emissions abatement, higher demands have been put on the development of highly efficient (i.e. active, selective and durable) catalysts.
