Figure 1From: Unique and facile solvothermal synthesis of mesoporous WO3 using a solid precursor and a surfactant template as a photoanode for visible-light-driven water oxidationSmall-angle and wide-angle X-ray diffraction patterns. (A) Small-angle and (B) wide-angle XRD patterns of WO3-DDA and WO3-bulk samples after being calcined at 400°C and 500°C. (a) WO3-DDA calcined at 400°C, (b) WO3-DDA calcined at 500°C, (c) WO3-bulk calcined at 400°C, and (d) WO3-bulk calcined at 500°C.Back to article page
