Popis: | Tuning the morphology of Ag 3 PO 4 photocatalysts with an elevated concentration of KH 2 PO 4 have been successfully conducted. This photocatalyst was prepared by starting material of AgNO 3 and KH 2 PO 4 . The KH 2 PO 4 aqueous solution with five concentrations of 0.10 M, 0.15 M, 0.30 M, 0.45 M, and 0.60 M was reacted with AgNO 3 aqueous solution. The products were characterized using X-ray Diffraction (XRD), UV-Vis Diffuse Reflectance Spectroscopy (DRS), and Scanning Electron Microscopy (SEM). The concentration of KH 2 PO 4 significantly affected the morphology, size, and crystallinity of catalyst. The morphology of Ag 3 PO 4 may be tuned with the synthesis using an elevated concentration of KH 2 PO 4 . The sample with the synthesis using 0.15 M of KH 2 PO 4 exhibited the excellent photocatalytic activity. The high photocatalytic activity was caused by the small size of mixed morphology of sphere and tetrahedron, high crystallinity and defect sites. Copyright © 2019 BCREC Group. All rights reserved |
