An alternative alkylpyridinium iodide with high electroactivity for efficient dye-sensitized solar cells

Alkyl-substituted pyridinium iodide has been applied as alternative iodide source in dye-sensitized solar cells (DSCs), featuring impressively high diffusivity and electroactivity. Encouraging energy conversion efficiency up to 8.23% was achieved, implying that this alkylpyridinium iodide serves as an effective alternative iodide source for DSCs. The intensity-modulated photocurrent/photovoltage spectroscopy measurements further indicated that the electron diffusion coefficient was considerably enhanced in device with pyridinium iodide electrolyte in comparison with that of the conventional imidazolium iodide, which was primarily due to a more shallow distribution of the surface trap states after the adsorption of pyridinium cations on the TiO(2) electrode surface.

Comparative study of forward and reverse ion exchange reaction in amberlite IRA-400 by application of tracer isotope-I-131

Iodide ion exchange reaction between the resin and solution phase can be represented by RI+I-(aq)* half arrow right over half arrow right RI*+I-(aq) where RI is the resin phase having exchangeable iodide ion, I* is the radioactive I-131 tracer isotope. This exchange of radioactive iodide ions and inactive iodide ions takes place reversibly. In the present investigation, kinetics study of forward and reverse ion exchange reaction was carried out in two sets of experiments: (1) exchange between radioactive iodide ions in solution and iodide ions on ion exchanger (forward exchange), (2) exchange between radioactive iodide ions on ion exchanger and iodide ions in solution (reverse exchange). This exchange study was performed at different temperatures from 27 degrees C to 48 degrees C, for different concentrations of potassium iodide solution from 0.0025 to 0.1 M and for different amounts of ion exchange resin ranging from 0.250 g to 5.00 g. The forward and reverse ion exchange reaction rates were observed to be 0.123 min(-1) and 0.122 min(-1) under identical conditions of 1 g ion exchanger at 27 degrees C and 0.01 M iodide ion solution indicating that forward and reverse ion exchange reaction occurs simultaneously.

Palladium-catalyzed reaction of aryl iodides with acetic anhydride. A carbon monoxide-free synthesis of acetophenones

[GRAPHICS] The palladium-catalyzed reaction of aryl iodides with acetic anhydride provides a straightforward and experimentally simple carbon monoxide-free route to acetophenones. The reaction tolerates a wide range of functionalized aryl iodides. Acetophenones are isolated in excellent yield with a variety of neutral, slightly electron-rich, and slightly electron-poor aryl iodides, whereas moderate yields are obtained with aryl iodides containing strongly electron-withdrawing substituents.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 88-67-5, in my other articles. SDS of cas: 88-67-5.

Formation of methyl iodide in the radiolysis of aqueous cesium iodide and acetic acid solutions

Volatile compounds of radioactive iodine, including methyl iodide, are released into the environment in the cases of serious accidents at nuclear power plants. The aim of this study was to find a conceivable mechanism of the radiation-chemical formation of methyl iodide in aerated aqueous solutions of cesium iodide and acetic acid. This provides the basis for subsequent investigations aimed at preventing the formation of methyl iodide. The radiation-chemical yield of methyl iodide formation in 10(-3) M CsI solutions containing CH3COOH (0.1 mol/l) decreased with increasing the pH. This fact is primarily explained by a decrease in the steady-state concentration of molecular iodine with increasing the pH. An increase in the pH of irradiated solutions up to pH greater than or equal to 9 was found not only to prevent the formation of methyl iodide but also to enhance its radiation-chemical degradation.
