Facile One-pot Synthesis of Silver Nanoparticles Supported on α-Zirconium Phosphate Single-Layer Nanosheets

In this paper, we report a facile one-pot synthesis method to prepare well dispersed silver nanoparticles (NPs) supported on α -zirconium phosphate ( α- ZrP) single-layer nanosheets. Silver NPs with a narrow size distribution were reduced on α- ZrP single-layer nanosheet surface due to the electrostatic attractions between the positively charged silver cations and the negatively charged α- ZrP nanosheet support. Three + reducing agents: glucose, NaBH , and tri-sodium citrate were used to reduce Ag . Transmission electron micrographs show that the reduced 4 silver NPs were well dispersed with a diameter of 18.3 ± 4.4 nm, 48.9 ± 13.8 nm, and 3.5 ± 1.0 nm when reduced by glucose, NaBH , and tri- 4 sodium citrate, respectively. Overall, we present a facile method to synthesize Ag NPs with various dimensions for widespread applications.
