摘要

采用简单的溶胶-凝胶法制备了纯二氧化钛纳米颗粒和掺杂二氧化钛纳米颗粒,并利用XRD、FTIR、UV-Visible和光催化分析对其结构、形态和特性进行了表征。通过XRD和SEM分析,发现了一种带有球形纳米颗粒的四方晶体结构。EDAX实验提供了二氧化钛存在于MnO2晶体基质中的额外证据。通过紫外光谱研究,确定了掺杂MnO2的带隙能。用亚甲基蓝(MB)和苯酚染料溶液在可见光照射下进行光降解研究。在理想条件下,MnO2掺杂催化剂对MB染料表现出优异的光催化效果

Characterizations of MnO2 doped TiO2 nanostructures and effective degradation of methylene blue dye under visible light irradition
Pure and TiO2 doped MnO2 nanoparticles were made using a simple sol-gel technique, and their structural, morphological, characteristics were characteristically examined using XRD, FTIR, and UV-Visible and photocatalytic analysis. Through XRD and SEM analyses, a tetragonal crystalline structure with spherical nanoparticles was discovered. The EDAX experiments provide additional evidence of TiO2's presence in the MnO2 crystal matrix. From UV spectral studies, the band gap energy of MnO2 doped was determined. Photo-degradation study was monitored using methylene blue (MB) and phenol dye solution under visible light irradiation. MnO2 doped catalyst displayed exceptional photocatalytic efficacy towards MB dye under ideal conditions
