摘要

结果表明，反应混合物中NH4(HF2)和Ti(BuO)4前驱体的摩尔比(X)的变化影响了共掺杂C、N、F-TiO2纳米结构的晶粒尺寸、SBET、Smeso、间隙碳含量以及紫外光照射下多西环素光降解过程的光催化活性。在可见光照射下，小X (X≤0.05)共掺杂锐钛矿/板岩形成光催化活性最高的异质结构。

Influence of Conditions of Preparation of C,N,F-TiO2 Nanostructures on Their Photocatalytic Activity in Doxycycline Photodegradation Process

It is established that the change in molar ratio (X) of NH₄(HF₂) and Ti(BuO)₄ precursors in the reaction mixture affects the crystallite sizes of the prepared co-doped C,N,F-TiO₂ nanostructures, their S_BET, S_meso, interstitial carbon content and photocatalytic activity in the doxycycline photodegradation processes under UV light irradiation. At small X (X ≤ 0.05) co-doped anatase/brookite heterostructures with the highest photocatalytic activity are formed under visible light irradiation.
