Generalized model for electron transfer at the interfaces of metal oxide/dye molecules/electrolyte and its application

Outline of Final Research Achievements

In order to elucidate the factors determining the electron transfer rates at the interfaces of metal oxides, organic dyes adsorbed on the oxide, and electrolyte containing redox couples, the electron transfer rates were measured for the combinations of various materials. For organic solvents, TiO2 absorbs more electrolytes than ZnO and SnO2. As a result, the interfacial electron transfer rates were different between the oxides. In addition, surface coverage of metal oxides by the adsorbed dyes was different, also resulting different electron transfer rates
