| 摘 要： | 用固相反应法制得的铝掺杂二氧化钛（Al-TiO2）材料研究了该材料在可见光下对吡啶的可见光降解性能，着重探讨了材料的微结构与可见光催化活性的关联．结果表明，处于热力学亚稳体系的锐钛矿型的Al-TiO2粉体材料，对吡啶的可见光降解活性远高于纯TiO2；其可见光催化活性与微晶尺寸呈正相关性，而与晶格畸变应力呈负相关性．Al... |

| Abstract: | Visible light degradation property of pyridine on the surface of Al-doped titanium dioxide materials prepared by a solid-state reaction was investigated.The correlations between microstructure and visible light catalytic activity of Al-doped TiO2 materials were emphatically discussed.The results show that visible light degradation activities of pyridine on anatase Al-doped TiO2 powder materials in a thermodynamics metastable state are higher than pure TiO2,and it is positive to crystallite size but negative... |
| Keywords: | Al-doped TiO2 pyridine conentration of microdefects catalytic activity |
