PHOTOCATALYTIC DEGRADATION OF RHODAMINE B USING Ag NANO DOPED TiO2 PREPARED BY -IRRADIATION METHOD
Vietnam Journal of Science and Technology - Tập 54 Số 4 - 2026
Nguyen Pham Tu Ngan, Do Quang Minh, Huynh Nguyen Anh Tuan, Vo Thi Thu Nhu, Nguyen Quoc Hien, Nguyen Ngoc Duy
Ag nano deposited on TiO2 (Degussa P25) (Ag nano/TiO2) photo-catalyst has been synthesized by g-irradiation method. The  characteristics  of  Ag nano/TiO2 material  has  been  investigated  by BET surface area, X-ray diffraction (XRD), transmission electron microscopy (TEM) and the diffuse reflectance spectra (DRS). The photo-catalytic properties of Ag nano/TiO2 for degradation of Rhodamine B in a... hiện toàn bộ

Low-temperature synthesis of superparamagnetic Zn0.8Ni0.2Fe2O4 ferrite nanoparticles
Vietnam Journal of Science and Technology - Tập 56 Số 1 - 2026
Nguyen Van Dan, Do Minh Nghiep, Luong Thi Quynh Anh
The crystalline nanoparticles of Ni0.2Zn0.8Fe2O4 ferrite were synthesized by chemical co-precipitation with precursor concentration of 0.1M, then modified by 0.25M solution of oleic acid in pentanol, finally heated at temperatures 120, 140, 160 and 180oC for 6h in autoclave. The XRD, EDS and TEM confirmed that all of samples are crystalline and their particle size are 6, 6.5, 7 and 8 nm. The magne... hiện toàn bộ
