1. one kind utilizes phenanthroline to close iron simultaneously to TiO 2the method of doping iron, nitrogen, is characterized in that:

  • (1) tetrabutyl titanate is dissolved in ethanol, ratio is 3mL tetrabutyl titanate/10mL ethanol;

    Add FeSO wherein again 47H 2o, ratio is 0.03gFeSO 47H 2o/10mL ethanol;

    (2) phenanthroline is dissolved in ethanol, ratio is 0.06g phenanthroline/10mL ethanol;

    (3) under constantly stirring, (2) gained solution is slowly added to (1) gained solution, mixes;

    (4) (3) gained solution is added to hydrothermal reaction kettle, by the centrifugation of gained solid, cleaning, oven dry after 180 DEG C of reaction 24h;

    (5), after (4) gained solid abrasive is thin, in Muffle furnace, namely product is obtained after 300 DEG C of calcining 4h.
