The electro-reduction process of iodate on Pt electrode in acidic solution is studied by means of galvanostatic transient, potentiostatic transient and polarization curve methods. The current time curve for potentiostatic transient exhibits a characteristic minimum point; the overpotential time curve for galva-nostatic transient exhibits a characteristic maximum point. The experimental results are quantitatively consistent with our previous work on the theoretical analysis for auto-catalytic electrode process....

A series of emulsions with the iodide content of 30mol% in core and with the core/shell ratio of 1:1, 1:2, 1:3, and 1:4 was prepared by combined core-precipitation and shell-formation with the double-jet technique. The micro-component analysis in the individual single crystal was conducted with the STEM-EDS method. It was shown that in the emulsion micro-crystal really exists the composite structure of iodide-rich core and iodide-poor shell, and what is more, the surface iodide concentration decreased with increasing core-shell ratio. The light absorption was measured by UV-240 spectrophotometer. The ionic and photo-electron conductivities were determined by dielectric loss measurement and microwave photo-conductivity method respectively. It was shown that the light absorption values for the 4 different emulsion microcrystals were found to be no essential difference as a result of the combined influence of two different contradictory factors the decrease of total iodide content and the increase of grain size of the microcrystals. The photo-conductivity signal intensity enhances with increasing core/shell ratio, the photoelectron lifetime becomes the longest for emulsion No.3, the core-shell ratio of which is 1:3. The corelations between the above-mentioned photophysical and electric properties, and the sensitometric behavour were presented and discussed.
