Development of new photocatalytic water splitting into H2 and O2 using two different semiconductor photocatalysts and a shuttle redox mediator IO3(super -)/I(super -)
Article Abstract:
A new type of photocatalytic reaction that splits water into H2 and O2 is designed using a two-step photoexcitation system composed of an iodate/iodide [IO3(super -)/I(super -)] shuttle redox mediator and two different photocatalysts, one for H2 evolution and the other for O2 evolution. Photocatalytic oxidation of water to O2 and reduction of IO3(super -) to I(super -) selectively proceeded with good efficiencies over TiO2-rutile and Pt-WO3 photocatalysts under UV and visible light irradiations.

Efficient eosin Y dye-sensitized solar cell containing Br(super -)/Br(sub 3)(super -) electrolyte
Article Abstract:
A study on Br(super -)/Br(super -)(sub 3) redox couple employed in dye-synthesized solar cells (DSSC) was performed. The study revealed that the Br(super -)/Br(super -)(sub 3) couple may be an alternative to the I(super -)/I(sub 3)(super -) couple of those dyes with more positive potentials than E(Br(super -)/Br(super -)(sub 3)) in DSSC in terms of good match between the highest occupied molecular orbital (HOMO) of the dye and the potential of the redox couple.

A CASPT2/CASSCF study of vertical and adiabatic electron transitions of acrolein in water solution
Article Abstract:
Two alternative methods are described for calculating solvent shift on adiabatic transitions and their performance is analyzed. A new method is proposed for calculating transition free energy in adiabatic transitions, where this method has avoided the classical calculation of the free-energy difference between the ground and excited-state.
