| titleOfInvention | Three-dimensional fluorine-nitrogen doped graphene/titanium dioxide composite material and preparation method thereof |
| abstract | A three-dimensional fluorine-nitrogen doped graphene/titanium dioxide composite material and a preparation method thereof relate to the field of nano composite materials. Firstly, adding graphene oxide into deionized water to prepare a graphene oxide dispersion liquid; then adding ammonium fluotitanate and urea into the graphene oxide dispersion liquid, uniformly dispersing, then carrying out hydrothermal reaction to obtain three-dimensional fluorine-nitrogen graphene/titanium dioxide gel, and carrying out freeze drying treatment to obtain a three-dimensional fluorine-nitrogen doped graphene/titanium dioxide pre-product; and finally, carrying out high-temperature calcination treatment on the three-dimensional fluorine-nitrogen doped graphene/titanium dioxide pre-product to obtain the three-dimensional fluorine-nitrogen doped graphene/titanium dioxide composite material. Through doping modification of fluorine and nitrogen elements, the conductivity and the electron mobility of the three-dimensional graphene are remarkably improved, the recombination of titanium dioxide photo-generated electron-hole pairs is effectively inhibited, the three-dimensional graphene provides a carrier for efficient transmission of titanium dioxide electrons, pollutants can be efficiently adsorbed, and the photocatalytic performance is further improved. |
