Type: article
Abstract: Take advantage of the 4f electron transition of Er ions and two-dimensional nanosheets, four kinds of ErBO3 powders with different morphologies were prepared by hydrothermal method and their properties were studied. The composition, crystallinity, morphology and specific surface area of the synthesized nanocomposites were characterized using XRD, FE-SEM, TEM, XPS, and BET methods. Thereafter, photocatalytic performances was investigated. Among them, the ErBO3(8) flower self-assembled by two-dimensional nanosheets exhibits the highest photocatalytic performance and the degradation rate of norfloxacin can reach 89.6% after 120 min illumination. Through the comparative analysis of the four powders properties, it was found that ErBO3(8) flower balls has the highest absorption efficiency in the visible region, the largest specific surface area, the lowest fluorescence intensity and the highest photocurrent, which are the main reasons for its high photocatalytic activity.
