Metal nanoparticles have interested in nanoscience and nanotechnology for applications as catalysis and storage battery. These materials possess high surface energy and are subject to aggregate upon preparation. Thus, considerable effort has been made to control the size and shape of the NPs for various applications. Herein, we have developed a simple procedure for the synthesis of Ag NPs deposited hollow porous organic nanospheres. The catalytic activity of the product was examined towards the reduction of methylene blue, 4-nitrophenol, and rhodamine B. The morphologies of the resultant Ag@HPONs were determined by SEM, TEM and X-ray diffraction. The surface area of these NPs was measured by BET, and the structural properties were characterized by FTIR, XPS. The producing Ag@HPONs have high surface area, low density, and high content of hydroxyl functional groups. They exhibited excellent performance in the reduction of methylene blue, 4-Nitrophenol and Rhodamine B at a mild condition. |
