Short iodide method
SpletPotassium and iodide codoped mesoporous titanium dioxide (TiO2) was synthesized via an improved sol-gel method using F127 and polyvinylpyrrolidone (PVP) as pore-forming agents. Due to the synergistic effect of codoped K and I, the light absorption of the catalyst is enhanced, and the separation efficiency of photogenerated charge is improved.
