Preparations and characterization of wolfram doped photocatalyst with mesoporous titanium dioxide (TiO2) via a sol-gel method

For the past two decades, the research of titanium dioxide was widely developed. The purpose of this study js to synthesize and characterize wolfram doped photocatalyst with mesoporous titanium dioxide (Ti0 2 ) via sol-gel method. The pristine mesoporous titanium dioxide (M-Ti0 2 ) and the doped mes...
