| Abstract: | The photocatalyst of TiO2/light ceramic was studied.Its proportion was close to water.It could be suspended and dispersed in water to increase its light level and water surface contact area and improve the photocatalytic activity.It could enhance its ability to degrade organic compounds.The results have shown that the photocatalyst of TiO2/light ceramic efficiency of the degradation of Rhodamine-B light is 12% higher than ordinary ceramic.The degradation efficiency of Rhodamine-B can reach 42 % when the hea... |
