采用等离子喷涂技术，在发泡废玻璃基板上用超声化学法将PtO2包覆的商品纳米TiO2粉(P25)固定化。在紫外光照射下，分别对绿潮和赤潮进行了固定化处理。考察了它们的光催化性能与残留藻类数量、透光率以及pH值随光照时间的变化关系。结果表明，在泡沫废玻璃表面等离子喷涂铂掺杂纳米二氧化钛涂层具有较高的光催化活性，对绿潮和赤潮的处理效果较好。
The commercial nano-sized TiO2 powder (P25) coated with PtO2 powder by a sonochemistry method was immobilized on the foamed waste-glass substrates by using plasma spray coating technology. The immobilized TiO2-Pt coatings were applied to treat both green tide and red tide under illumination of an UV light. Their photocatalytic characterizations were evaluated as functions of the number of residual algae, transmission as well as pH value with illumination time. It’s found that the plasma sprayed Pt-doped TiO2 nanostructured coatings on foamed waste-glass showed higher photocatalytic activity, which was effective to treat the green tide and red tide.
