采用旋转填充床反应器在室温下反应1 min制备Mg（OH）2/氧化石墨烯（MGO）复合材料。片状Mg（OH）2纳米晶体直径约为60 nm，尺寸分布较窄，均匀分布在氧化石墨烯片上，没有聚集现象。具有介孔结构的MGO的比表面积达到590 m2 g-1，这是文献中报道的最高的。所制备的MGO纳米复合材料对亚甲基蓝（MB）具有良好的吸附性能。在1 min内，MB的去除率可达98%。MGO纳米复合材料的制备工艺快速、简单，适合大规模生产，在环境保护领域具有很大的应用潜力。
A facile high-gravity strategy is proposed for preparation of Mg(OH)2/graphene oxide (MGO) composite using a rotating packed bed reactor at room temperature for 1 min. Lamellar Mg(OH)2nanocrystals of about 60 nm in diameter with a narrow size distribution are distributed homogeneously on the graphene oxide sheets without aggregation. The specific surface area of MGO with mesoporous structure reaches 590 m2g−1, which is the highest among those reported in the literatures. The as-prepared MGO nanocomposite exhibits excellent adsorption capacity for methylene blue (MB). The removal rate of MB reaches 98% in 1 min. The preparation process of MGO nanocomposite is rapid, simple, and suitable for a large-scale production, and the product has great potential in the field of environmental protection as a promising absorbent.
