ynthesis of MoO3/Ag nanotube was performed successfully using Palmer amaranth and characterized by EDAX and SEM. The presence of MO,Agand O was confirmed and nanotube shape of it was proved using SEM image. Also, MoO3nanoparticles was fabricatedfrom Amaranthus spinosusand characterized by XRD, EDAX and elemental analysis. The crystalline structure of it and presence of Mo and O were proved.
