Size-controlled synthesis of palygorskite/Ag3PO4 nanocomposites with enhanced visible-light photocatalytic performance
AbstractThe synthesis of nanoparticles with a tight control on their sizes is a requirement for many nanotechnologies and application goals. Herein, a simple method has been reported to prepare size-controlled Ag3PO4 nanoparticles deposited on the surface of palygorskite (PAL) nanorods (called as PAL/Ag3PO4 nanocomposites). The particle size of Ag3PO4 could be well controlled by adjusting the concentration of PAL due to its typical negative surface charges and specific colloidal-rheological properties. Results show that the optimal content of PAL (20mass%) could be selected to obtain the perfect Ag3PO4 nanoparticles with the average diameter size of 10nm and the visible-light photocatalytic activity and stability of PAL/Ag3PO4 nanocomposites for degrading 10mg/L methyl orange (MO) solution were enhanced. This new work can provide a promising strategy for controllable preparation and efficient application of nanomaterials.
HighlightsThe size-controlled Ag3PO4 nanoparticles deposited on the surface of palygorskite nanorods were prepared.The size of Ag3PO4 nanoparticles can be tuned by using raw palygorskite with surface negative charges.The enhanced mechanism mainly relied on the particle size of Ag3PO4.
