ผลของสารเจือไอออนลบต่อ BiOl ที่สังเคราะห์ด้วยวิธีอัลตร้าโซนิคสำหรับการสลายตัวด้วยตัวเริ่งปฏิกิริยาทางแสงของโรดามินบี

Abstract

BIOI, F-doped Biol and Br-doped BIOI photocatalysts were synthesized by ultrasonic method. The as-prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and X-ray photoelectron spectroscopy (XPS). They found that as- prepared samples were tetragonal BIOI phase and clearly revealed the presence of BIOI nanoplates, F-doped BIOI nanobelts and Br-doped BiOI nanobelts. Doped ions were successful incorporated in the BIOI lattice. Their photocatalytic activities were evaluated through the degradation of rhodamine B (RhB) under visible light irradiation. In this research, the 10 wt% F-doped BiOI and 10 wt% Br-doped BIOI have the highest photocatalytic activity of almost 100% and 98.88% within 180 min.
