研究目的
Investigating the photocatalytic degradation mechanism of Reactive brilliant blue X-BR by expanded perlites loaded titanium dioxide photocatalysts.
研究成果
The crystalline titanium dioxide prepared by sol-gel method is anatase which has a good performance of photocatalytic oxidation, loaded on the expanded perlite can be a kind of efficient adsorption catalyst which can float on the surface of water and easy to be recycled. The degradation of X-BR in aqueous solution by photocatalysis oxidation is that hydroxyl radicals firstly attacked the chromophore which arounded the anthraquinone ring and made it destruction and decolourization; then the groups such as naphthoquinone, benzene, etc. which were easily to be oxidized were attacked. Finally, the triazine structure degraded. The degradation of intermediates mineralized into inorganic substances ultimately after a series of process.
研究不足
The study focuses on the photocatalytic degradation mechanism under specific conditions and may not cover all possible environmental or industrial applications.
