Semi-conductor multi-phase light catalyst technology can directly use the sunlight and oxygen in air to degrade completely the toxic pollutants in environment and make them nontoxic small-molecular compounds, so it is a new environmental-friendly technology to solve pollution. However, the obvious problem keeping this technology from mass application is the existed light catalyst does not have good absorption of visible light and low quantum efficiency, so the solar power utilization rate is low. Besides, there has been no way to solve it so far.
以上是第一段。 |
