Abstract

In this research work, pure and lanthanum (La)-doped copper oxide nanoparticle (CuO-NPs) are synthesized using a sol-gel technique which is quite simple, efficient and cost-effective as well. Various characterization techniques have been employed to investigate the effect of rare earth dopant (La) on morphological, compositional, structural, optical, and vibrational properties of fabricated nanomaterial which is tested as potential photo catalyst. Quite interestingly, the bandgap was reduced by the introduction of dopant element. Additionally, the average particle size was also reduced for doped samples. Degradation of methylene blue (MB) was investigated under UV visible light for 100 min in the presence of synthesized photocatalysts. The best efficiency of 80% is achieved by 2% La-doped sample attributed to Burstein-Moss effect. Experimental results are well consistent with the results of the simulation which were realized while using finite element analysis (FEA) technique in RF module (version 5.3a) of COMSOL Multiphysics. This simulation technique helped to understand the insight about the various aspect of the photocatalytic process reported here.
