文摘

Bulk defects were reduced by SiO2-shell-enhanced F modification. Surface Ti3+ were increased by SiO2-shell-enhanced F modification. Surface doped F was increased by SiO2-shell-enhanced F modification. F doping in lattice was inhibited by SiO2-shell-enhanced F modification. Surface doped F acted as catalytic site whereas lattice F induced bulk defects.
