| Ag@AgI Supported TiO2 Acid Corrosion Nanobelts Plasma Photocatalyst: Synthesis and Visible Light Photocatalytic Performance | |
| 摘要: 采用沉积-沉淀法将AgI分散到TiO2酸蚀纳米带上，然后通过光照进而分解出Ag颗粒，最终获得了Ag@AgI等离子体负载的TiO2酸蚀纳米带(AIST)。利用UV-Vis吸收光谱、XRD、SEM对产物进行表征，并研究了可见光下对甲基橙(MO)的光催化降解性能。结果表明，纳米带酸蚀后利于AgI的沉积，Ag的表面等离子体共振效应可以增强催化剂对于可见光的吸收，使可见光下AIST的光催化降解性能显著提高。 | |

| Abstract: A Ag@AgI supported TiO2 acid corrosion nanobelts plasma photocatalyst was prepared by deposition-precipitation method and photo reduction method. The products were characterized by XRD, SEM and UV-Vis spectroscopy. The photocatalytic activity was evaluated using methyl orange (MO) degradation under visible light irradiation as a probe reaction. The results indicate that the corrosion nanobelts are beneficial for AgI deposition. The surface plasmon resonance of Ag can enhance the visible light absorption of photocatalyst. The TiO2 acid corrosion nanobelts supported with Ag@AgI photocatalyst show the highest photodegradation of MO under visible light. | |
