Abstract

The pure, tin (Sn)-doped, lanthanum (La)-doped and Sn/La co-doped titanium dioxide (TiO) nanomaterials were synthesized using sol-gel method followed by calcination at the temperature of 360 °C, 450 °C and 600 °C, respectively. The structures of the nanomaterials were characterized by X-ray diffraction (XRD), Thermogravimetric (TG), Differential Thermal Analysis (DTA), Scanning Electron Microscopy (SEM), Energy Dispersive Spectrum (EDS), Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectrum (XPS), Diffuse Reflectance Spectrum (DRS), Photoluminescence Spectrum (PL), Brunauer-Emmett-Teller Measurements (BET), respectively. The photocatalytic property of the photocatalysts under UV light was evaluated through the degradation of Rhodamine B (RhB). The results show that the anatase-rutile phase transition is promoted by Sn-doping while La-doping retards the phase transition. However, La doping plays a major role in the process of phase transformation. The photocatalytic activity of pure TiO is affected by annealing temperature remarkably and the optimal annealing temperature is 450 °C. The photocatalytic activity of TiO is enhanced significantly by Sn and La doping at three different temperatures. Sn/La-TiO exhibits the highest degradation rates and the fastest reaction rates probably owing to the synergistic effect of Sn and La ions in inhibiting the recombination of photogenerated electron-hole pairs. The formation of extra surface hydroxyl groups and additional surface area are also beneficial for the photocatalytic activity.

摘要

采用溶胶-凝胶法合成了纯二氧化钛（TiO₂）、掺锡（Sn）、掺镧（La）以及锡/镧共掺杂的二氧化钛纳米材料，随后分别在360℃、450℃和600℃的温度下进行煅烧。通过X射线衍射（XRD）、热重分析（TG）、差示热分析（DTA）、扫描电子显微镜（SEM）、能谱分析（EDS）、透射电子显微镜（TEM）、X射线光电子能谱（XPS）、漫反射光谱（DRS）、光致发光光谱（PL）、布鲁诺尔-埃米特-泰勒测量法（BET）对纳米材料的结构进行了表征。通过罗丹明B（RhB）的降解评估了光催化剂在紫外光下的光催化性能。结果表明，掺锡促进了锐钛矿-金红石相转变，而掺镧则延缓了该相转变。然而，镧掺杂在相变过程中起主要作用。纯TiO₂的光催化活性受退火温度影响显著，最佳退火温度为450℃。在三个不同温度下，Sn和La掺杂显著提高了TiO₂的光催化活性。Sn/La-TiO₂表现出最高的降解率和最快的反应速率，这可能归因于Sn和La离子在抑制光生电子-空穴对复合方面的协同效应。额外表面羟基的形成和增加的表面积也有利于光催化活性。
