文摘
- •
Zinc-copper silicate polymer was synthesized as a robust and stable ozonation catalyst for the first time.
- •
Hydroxylated zinc and Hydroxylated copper were the main active composites.
- •
Surface hydroxyl groups and chemisorbed water acted as catalytic active sites.
- •
The transformation from ozone to hydroxyl radicals was responsible for catalysis.
