Microwave Photoconductivity Intensity (IMAGE) Osaka University Caption (a) Product of microwave photoconductivity intensity and its lifetime of oxyhalide photocatalyt 2 vs calcination temperature. The microwave measurements suggest the optimal temperature of 600 ? that is 100 ? lower than the reported one. (b) O2-evolution rate of oxyhalide photocatalyt 2 prepared by different calcination temperature.
