▎ 摘　　要

NOVELTY - Preparing doping modified titanium dioxide/graphene composite material comprises using sol-gel method, doping rare earth element lanthanum, yttrium and transition metal ion into titanium dioxide to obtain doping modified titanium dioxide, and then through hydrothermal reaction, and loading the doped modified titanium dioxide on graphene oxide material. USE - The composite material is useful for degrading organic pollutants. ADVANTAGE - The composite material: is visible under infrared conditions; has catalytic activity; and increases the sunlight utilization.
