Study on Preparation Condition and Degradation of Wastewater with TiO2-Coated Activated Carbon
TiO2 has its advantages in terms of degeneration of wastewater. However, dispersing Nano-TiO2 in water will make it hard to recycle and produce a giant waste of raw material, which would affect its prospect as a practical application. The main problem in the practice of photocatalytic technology is to prepare stable and highly active Nano-TiO2. It is a good way to prepare supported TiO2 by absorbing the active component of TiO2 to the surface of activated carbon. In this paper, we use activated carbon as the carrier and prepare supported TiO2 catalysts by the hydrolysis of titanium sulfate precipitation method. Then, we use active red X-3B to simulate the wastewater to study catalyst preparation methods and the factors that affect the photocatalytic performance.
