Photocatalytic Reduction of CO2 to Formaldehyde: Role of Heterogeneous Photocatalytic Reactions in Origin of Life Hypothesis
Photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (FeS, FeS/FeS2, NiO and TiO2). The reaction was carried out in continues flow of CO2 gas bubbled into the reactor. Semiconductor photocatalysts were characterized by X-Ray diffraction (XRD) and Diffuse Reflectance Spectroscopic (DRS) methods. Sulfide ion was used as hole scavenger. T...

متن کاملKinetic Concepts of Heterogeneous Photocatalysis
TheABCs of empirical chemical kinetics are highlighted from the scratch. Aspects of dynamics regarding charge carrier trapping and recombination are essential part of this discussion. The effect of imposition of external constrains such as temperature of the reactivity solution, concentration of the subject compound, intensity and wavelength of light on photocatalytic degradation system is emph...

متن کاملGreen oxidation of alcohols to carbonyl compounds by heterogeneous photocatalysis.
The selective conversion of alcohols to carbonyl compounds is essential for the preparation of fragrances, food additives, and many organic intermediates. This transformation is carried out by catalytic processes that are of fundamental importance in synthetic chemistry. Catalytic oxidation has long been carried out in environmentally harmful organic solvents (often chlorinated ones) at high te...
