文摘
- •
Surface thermosynthesis was applied for supporting FeOx on glass fibers.
- •
Support modification with external silica layer increases the content of FeOx.
- •
Highly dispersed surface and subsurface FeOx particles (1–2 nm) are observed.
- •
Isolated Fe3 + Oh cations are stabilized in the layers of SiO2 secondary support.
- •
New catalyst activity exceeds the activity of conventional one by more than 10 times.
