摘　　要：以氧化石墨烯(GO),稀土金属氧化物氧化铈(CeO_(2))为原料,采用水热法制备了GO-CeO_(2)复合气凝胶,在自然光光催化的条件下研究了甲基橙(MO)初始浓度,光催化时间对复合气凝胶光催化性能的影响。结果表明:当浓度为15 mg/L时,GO-CeO_(2)复合气凝胶的降解效果最好,100 min时达到99%。The GO-CeO_(2) composite aerogel was prepared by hydrothermal method from graphene oxide(GO)and rare earth metal oxide cerium oxide(CeO_(2)).The initial concentration of methyl orange(MO)and the effect of photocatalytic time on the photocatalytic performance of the composite aerogel were studied under the condition of natural photocatalysis.The results showed that when the concentration was 15 mg/L,the degradation effect of GO-CeO_(2) composite aerogel was the best,reaching 99%after 100 min.
