Synthesis route for nanoparticles:Step 2 Surface coating with surfactantA surfactant‐assisted synthesis route was developed to formMetal‐Phn nanoparticles, without external energy input.
Synthesis schematicSyringePumpVariable conditions include:TemperatureTitration speedpHCa vs. Phn mass ratio24mL PhosphoatepH=9.150mL 80 o CCaCl 2/ZnCl 2and surfactant• The metal-Phn precipitate was formed instantaneouslyupon injection of phosphonate under constant stirring;• Optimal synthetic condition was chosen asLow injection rate, 80 o C, pH=6.5 and M: Phn=4.5
