活性炭纤维负载镧氮共掺杂二氧化钛复合催化剂可见光下光催化性能研究

PHOTOCATALYTIC DEGRADATION ACTIVITY OF ACF LOADING La AND N CO-DOPED TiO2

制备了活性炭纤维负载镧氮共掺杂二氧化钛复合光催化剂ACF，TLN·并在可见光下降解甲基橙以考察其催化活性。并在同等奈件下，对负载未掺杂二氧化钛的活性炭纤维样品ACFT1和未负载二氧化钛的空白活性炭纤维样品ACFT1进行了对比实验。结果表明，在可见光下ACFTLN降解能力ACACT1和ACF。其降解能力是吸附性能和光催化性能的协同作用，并拥有较好的可见光响应性。

Activated carbon fiber（ACF）loading titanium dioxide co-doped with La3~ and N（ACFTLN）was prepared by sol- gel method.The photocatalysis characteristic of ACFTLN was researched in the experiment of disintegrating of methyl orange under visible light.ACF loading co-doped TiOE（ACFTi）and un-loaded ACF（ACF0）were also tested in the same conditions.The results indicate that the photocatalytic degradation efficiency of ACFTLN is better than those of both ACFTI and ACF0.And the reason is ascribed to the synergy of absorption and photoeatalytic performance, moreover, the spectral response of ACFTLN to visible light is the best among all samples.
