Abstract In the present work, uniformly distributed Lanthanum Oxide nanoparticles on poly (tetrahydrofurfuryl methacrylate) brushes spread over the surface of reduced graphene oxide (La2O3/PTHF/rGO) are synthesized. La2O3/PTHF/rGO is used as catalyst for the degradation of Rhodamine B (RhB), Methyl Orange (MO) and Eosine Y (ESY) dyes. Catalyst has shown excellent catalytic activity as evident by the apparent Rate constant (kapp), which is found to be 26.8, 28.6, and 20.5 (×10−3 s−1), for RhB, MO and ESY respectively, much higher than the reported in literature. The catalyst is recycled for five times without any significant loss in its activity, which makes it suitable for the applications in catalysis and waste water management.

氧化镧纳米粒子固定还原氧化石墨烯聚合物刷纳米杂化物用于有机染料的环境破坏

摘要 在目前的工作中，合成了分布在还原氧化石墨烯 (La2O3/PTHF/rGO) 表面上的聚（甲基丙烯酸四氢糠酯）刷上均匀分布的氧化镧纳米颗粒。La2O3/PTHF/rGO 用作降解罗丹明 B (RhB)、甲基橙 (MO) 和曙红 Y (ESY) 染料的催化剂。催化剂表现出优异的催化活性，表观速率常数 (kapp) 表明，RhB、MO 和 ESY 的表观速率常数 (kapp) 分别为 26.8、28.6 和 20.5 (×10-3 s-1)，远高于文献中报道。该催化剂循环使用五次，其活性没有任何显着损失，适用于催化和废水管理方面的应用。
