摘　　要：为提高光催化材料的效率,实现材料的绿色化,以木质纤维素为原料,以TiO_(2)为催化材料,通过掺杂Ni-NiO/Fe_(3)O_(4)-GR制备了磁性光催化材料。结果表明:不同添加量的Fe_(3)O_(4)-GR(G1F1)对亚甲基蓝的光催化效率明显不同,在光催化材料复合物中,当G1F1添加量占木质纤维素质量的8.3%时,其光催化效率可达91.92%,显示出优异的光催化性能。In order to improve the efficiency of photocatalytic materials and realize the greening of materials,in this study,the magnetic photocatalytic materials were prepared by doping Ni-NiO/Fe_(3)O_(4)-GR with lignocellulose as the initial material and TiO_(2)as the catalytic bulk material.The results showed that the photocatalytic efficiency of methylene blue was significantly different with different proportions of Fe_(3)O_(4)-GR(G1F1).When the addition of photocatalytic material complex G1F1 was at 8.3%of the mass of lignocellulose,the photocatalytic efficiency could reach 91.92%,indicating excellent photocatalytic performance.
