N 2 sorption isotherms and pore size distribution. (A) N2 sorption isotherms and (B) pore size distribution of WO3-DDA and WO3-bulk samples after being calcined at 400°C and 500°C. In N2 sorption, isotherm adsorption and desorption points are marked by filled and empty symbols, respectively. (a) WO3-DDA calcined at 400°C, (b) WO3-DDA calcined at 500°C, and (c) WO3-bulk calcined at 400°C.
