| บทคัดย่อ/คำอธิบาย | : | A simple and inexpensive method to form a hematite photoanode for efficient water oxidation is reported. A very thin ZnO overlayer was deposited on top of a thin film of hematite and found, compared with non-treated hematite, to increase the photocurrent and reduce the onset potential for generating oxygen from water. After 3 cycles of ZnAc treatment, the photocurrent increased more than 40% to 1.08 mA/cm-2 at 0.23 V vs Ag/AgCl and onset potential for water oxidation shifted by -170 mV. It is proposed the ZnO overlayer changes the flat band potential of hematite and reduces the surface defects. |
