The valorization of carbon dioxide and its transformation into useful chemicals is essential as mankind consumes more and more fossil fuels, thus producing equivalent wastes. The storage of hydrogen, a promising energy carrier, is also of great interest in ...
Owing to the problems associated with the use of urea as an ammonia precursor compound in the selective catalytic reduction process in automobiles, alternative compounds such as ammonium formate, methanamide, and guanidinium formate have been suggested as ...
In homogeneous catalysis, the structure and electronic config-uration of the active catalysts can vary significantly. Changes inligation, oxidation, and spin states have the potential to influ-ence the catalytic cycle energet ics strongly that, to a larged ...
CeO2-based nanomaterials and their rich redox chemistry provide a possible route to pollutant abatement in various heterogeneous processes, and are in particular used as sorbents for flue gases and as oxygen promoters in three-way catalytic converters. The ...
Log wood burning is a significant source of volatile organic compounds including aromatic hydrocarbons (ArHC). ArHC are harmful, are reactive in the ambient atmosphere, and are important secondary organic aerosol (SOA) precursors. Consequently, SOA represe ...
The methanol dehydration reaction was studied over environmentally benign, easily accessible and inexpensive K10 montmorillonite clay used as the catalyst at a temperature range between 200–700 °C. Nearly 100% selectivity towards dimethyl ether (DME) at 80 ...
The industrial production of aromatic amines, essential intermediates for the synthesis of several drugs, dyes, pigments and agrochemicals, requires the use of heterogeneous catalysis. These molecules were formerly produced by the Béchamp reduction, a non- ...
The main aim of this dissertation is to study the catalytic aspects of very small transition metal clusters supported on h-BN/Rh(111). The catalytic reactions of interest were ammonia synthesis and CO oxidation on mass selected and soft landed iron and pla ...
Catalytic methane oxidation is used in exhaust gas after treatment to reduce methane emissions in stationary combustion processes as well as in natural gas vehicles. Pd/zeolite catalysts provide higher activity than the commonly used Pd/Al2O3, but suffer f ...
The most efficient after-treatment technology for reducing harmful NOx emissions from stationary and mobile sources of diesel exhaust is the selective catalytic reduction (SCR) of NOx with ammonia (NH3). Vanadium-based SCR catalysts reduce NOx selectively ...
