摘要

几种纳米颗粒(Cu2O、SnO、ZnO)在废水处理研究中得到了广泛的研究和应用，其中TiO2因其稳定性、可负担性、大带隙、可回收性和光催化效率等优点而受到人们的青睐。本研究报道了增溶基质对TiO2纳米颗粒合成的影响。采用湿化学法将二氧化钛溶解于水、甲苯和二氯甲烷三种溶剂中，合成了二氧化钛纳米颗粒。采用XRD、UV-Vis、FTIR和SEM对不同增溶剂制备的TiO2纳米粒子的物理、化学和光学性质进行了表征。结果表明，TiO2纳米粒子在不同溶剂下的水溶性具有最佳的性能。关键词:氯化钛，氧化钛，纳米材料，湿化学法

Impact of Solubilising Matrices for TiCl4 on the Formation of TiO2 Nanoparticles

Several nanoparticles (Cu2O, SnO, ZnO) have been intensively studied and applied in wastewater treatment research, with TiO2 gaining popularity because of its stability, affordability, large band gap, recyclability and its efficiency in photocatalysis. This study reports on the influence of solubilising matrices on TiO2 nanoparticle synthesis. A Wet Chemical Method was used to synthesis TiO2 nanoparticles by solubilising TiCl4 in three types of solvents: water, toluene and methylene chloride. Physical, chemical and optical properties of the TiO2 nanoparticles obtained from these various solubilising agents were characterised by XRD, UV-Vis, FTIR and SEM. Results were compared for each solvent with TiO2 nanoparticles solubilised in water having the best properties. Keywords—Titanium Chloride, Titanium Oxide, Nanomaterials, Wet Chemical Method
