| 摘 要： | 以钛酸四丁酯、硝酸铁、硝酸铬为原料，采用改进的溶胶凝胶法制备铁-铬共掺杂的二氧化钛纳米球。对该纳米球进行了结晶结构、形貌和光吸收性质方面的表征，测试了该纳米球在紫外可见光照射下光催化产氢活性。结果表明，在掺杂量不变的情况下，铁-铬共掺杂二氧化钛纳米球获得最好的光催化活性(133.6 μmol/g/h)，并且具有优秀的光催化稳定性。 |

| Abstract: | The Fe-Cr co-doped TiO2 nanosphere were synthesized with Titanium butoxide, Iron (III) nitrate nonahydrate, Chromium (III) nitrate nonahydrate by a modified sol-gel method. The crystal structure, morphology and optical absorption property of as-prepared nanosphere were characterized. And the photocatalytic hydrogen evolution was performed under UV-vis light illumination. It turned out that the Fe-Cr co-doped TiO2 nanosphere obtains the best photocatalytic hydrogen evolution activity (133.6 μmol/g/h) and also exhibits high reusability for photocatalytic reaction. |
