Diffuse-reflectance infrared Fourier transform (DRIFT) spectroscopy has been used to study in situ, the low-temperature (T < 200°C) methanation of CO2 over Ru on TiO2 supports and on Al2O3. For 3.8% Ru/TiO2, the reaction exhibits an activation energy (Ea) ...
A process and device are disclosed for purifying liquids, in particular water, contaminated with inorganic and/or organic impurities. The impurities are transformed and/or precipitated through the use of the catalytic and photocatalytic properties of semic ...
A complete system for cleavage of water by light (250‐W lamp) comprises the catalysts Pt and RuO2 and the sensitizer Ru(bpy) as well as the acceptor methylviologen (MV2+). 150 ml of solution gave 0.6 ml of H2 and 0.3 ml of O2 in h. ...
Supported palladium oxide catalysts are able to convert CH4 to C2H6, CO, CO2, H2 and H2O at temperatures ⩾315 °C. Catalysts did not show any support effect when TiO2, Al2O3, ZrO2, La2O3 and MgO were used as supports. With sequential O2 pulsing the catalyst ...
The use of formate-based ammonia precursors as alternatives to urea in the selective catalytic reduction (SCR) process requires that formic acid released upon their thermolysis in the hot exhaust is rapidly decomposed to carbon dioxide. This work aims at t ...
A regenerative photoelectrochemical cell (1) including a first transparent substrate (2) comprising a first transparent electrode (6), and a second transparent substrate (4) comprising a second transparent electrode (8) on which a first photoelectrochemica ...
The sensitization of a semiconductor-based oxidoreduction photocatalyst is carried out by fixing at its surface a colour carrier comprised of a fragment of a transition metal complex such as ruthenium, chromium or iron and of a ligand of the bipyridyl or p ...
Studies have been carried out on aqueous colloidal suspensions of semiconductors, principally by using laser flash-photolysis techniques, in order to scrutinize in detail the dynamics of light-induced charge transfer reactions occuring at the solid-electro ...
Recently, polymeric carbon nitride (g-C3N4) as a proficient photo-catalyst has been effectively employed in photocatalysis for energy conversion, storage, and pollutants degradation due to its low cost, robustness, and environmentally friendly nature. The ...
