2.5. Preparation of Porous Magnetic PMMA Microspheres The PMMA-COOH microspheres (0.1 g) were transferred into a 250 mL three -necked round-bottom flask, and then 30 mL of a 0.043 g FeCl2·4H2O, 0.118 g FeCl3·6H2O solution were added to the flask and stirred for 5 h under a nitroge...
After 16 h at 80 ◦C, the mixture was cooled to room temperature, and 1N HCl and AcOEt were added. The mixture was extracted twice with AcOEt, and the combined organic phase was washed with a saturated solution of NaHCO3, brine, and concentrated under reduced pressure. To remove the ...
A 20 mL mixed solution containing 1 M FeCl3·6H2O and 1 M Na2SO4 was prepared first, and then 0.5 mL TiCl4 ice water with a concentration of 40 mM was added. Then FTO substrate was put into a Teflon-lined stainless steel autoclave that was filled with 2.5 mL solution. The reaction...
