Abstract
Herein, a concise one-pot method to prepare magnetic yolk–shell composite nanoparticles (MYSCNPs) is developed. Phenolic resin microspheres act as sacrificial templates for depositing SiO2, and Fe@SiO2 is used as the shell-forming promoter. The diameters of MYSCNPs are [Formula: see text] nm. MYSCNPs have magnetic performance, and both the yolk and shell of MYSCNPs are mesoporous. LaCl3 catalysts are loaded onto MYSCNPs to prepare loaded LaCl3 catalysts (LaCl3-lo-MYSCNPs). Using sodium borohydride (NaBH[Formula: see text] and LaCl3-lo-MYSCNPs, liquid terminated-carboxyl fluoropolymers (LTCFs) are efficiently reduced to the corresponding liquid terminated-hydroxyl fluoropolymers (LTHFs). The structures of LTCFs and LTHFs are analyzed using FTIR and 1H-NMR. The results show that C=C and COOH of LTCFs are successfully reduced to C–C and OH.
