A Facile Synthesis of La₂O₃/GO Nanocomposites in N,N-Dimethylformamide with High Dye Degradation Efficiency

Abstract

La 2 O 3 /graphene oxide (GO) nanocomposites were simply synthesized from commercially available LaCl 3 ⋅7H 2 O and multilayer GO (5-10 layers) in N,N-dimethylformamide (DMF) under reflux condition without extra stabilizer. The characterization results of scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectrum (XPS) spectroscopies showed that the crystalline La 2 O 3 nanoparticles were successfully attached on the surface of GO. Moreover, the as-prepared nanocomposites greatly enhanced the degradation efficiency of organic dyes after 15 min under ultrasound irradiation in pure water. The degradation efficiency of the nanocomposites for methylene blue could be over 99%.

Efficient Dye Degradation and Antibacterial Activity of Carbon Dots/Chitosan-Doped La2O3 Nanorods: In Silico Molecular Docking Analysis

“…Arshad et al reported that Ni-doped La 2 O 3 reveals the highest photocatalytic degradation of 99.15% in 30 min . According to He et al, GO-doped La 2 O 3 exhibited a degradation potential for RhB of 63.2% in 15 min …”
