| 摘要 |
The present invention relates to a photocatalytic oxidation material comprising a) about 30% w/w to about 40% w/w titanium dioxide crystals having crystal size of about 3 nm-25 nm and crystallinity of at least 70%; b) about 50% w/w to about 60% w/w polyethylene glycol as dispersant; and c) 1-10 %w/w water, wherein said titanium dioxide crystals comprise surface hydroxyl groups, wherein 90%-100% of said surface hydroxyl groups are characterized by at least one absorption peak within an infrared spectrum range between 3000-3680cm -1 when recorded at 150°C. |
