Recent research on photocatalytic activities has been investigated using visible light region rather consuming ultraviolet region. In this Paper, a facile and eco-friendly method was developed to the synthesis of TiO2 NPs using Aloe Vera gel (AV-TiO₂). The synthesized nanoparticles were characterized using XRD, XPS, HRTEM, EDAX and Raman spectroscopy. The sharp peaks by XRD pattern show the crystallinity and purity of titanium dioxide nanoparticles. The shape and morphology were studied by HR-TEM images and confirms the NPs size which falls in the range from 6 to 13 nm. Raman spectrum and XPS shows the energy modes and oxidation state of synthesized TiO₂ NPs. TiO₂-mediated photo-degradation of trinitrophenol (Picric acid- PA) irradiated by visible light source has also been investigated.

已经使用可见光区域而不是消耗紫外线区域来研究光催化活性的最新研究。本文研究了一种简便而环保的方法，用芦荟凝胶（AV-TiO ₂）合成TiO2 NP 。使用XRD，XPS，HRTEM，EDAX和拉曼光谱对合成的纳米粒子进行表征。XRD图谱的尖峰表明了二氧化钛纳米颗粒的结晶度和纯度。通过HR-TEM图像研究了形状和形态，并确认了NPs的大小在6至13nm的范围内。拉曼光谱和XPS显示了合成的TiO ₂ NPs的能量模式和氧化态。二氧化钛₂还研究了可见光对三硝基苯酚（Picric acid- PA）介导的光降解作用。
