Figure 6From: Unique and facile solvothermal synthesis of mesoporous WO3 using a solid precursor and a surfactant template as a photoanode for visible-light-driven water oxidationPhotocurrent density versus time profiles during PEC water oxidation using samples calcined at 500°C. (a) ITO/WO3-DDA and (b) ITO/WO3-bulk electrodes in 0.1 M phosphate buffer solution of pH = 6.0 at 0.5 V versus Ag/AgCl with visible light irradiation (λ > 390 nm, 100 mW cm-2).Back to article page
