采用XRD和UV-Vis漫反射光谱对一种绿色SiC微粉进行了表征，并研究了其光催化分解水的性能。结果表明，绿色SiC微粉在可见光照射下能吸收可见光，分解水并产生氢气。活性受溶液初始pH值和廉价试剂类型的显著影响，其中添加OH-或S2-导致活性显著增加。
A kind of green SiC fine powder was characterized by XRD and UV-Vis diffuse reflectance, and studied in the photocatalytic splitting of water. The results showed that the green SiC fine powder can absorb visible light and split water with the formation of hydrogen under visible light irradiation. The activity is affected significantly by the initial pH of solutions and the types of cheap reagents, where the addition of OH−or S2−leads to a remarkable increase in the activity.
