Investigation on structural, particle size of nano particles for visible light photocatalytic dye degradation

Abstract

The sol–gel approach is used to prepare the undoped TiO2 and Zr/P doped nano photo catalysis. The XRD pattern reveals that the lattice parameters of all the samples are almost comparable, indicating that no structural changes have occurred. E-Dax spectrums of photo catalysis confirm that the Weight% and Atomic% of every element in each nanoparticle exactly match the desired Weight% of every element in the preparation of nanoparticles. TEM exhibits the average particle size of the 0.25Zr1PT is 8.023 nm and this size of various particles in 0.25Zr1PT is in accordance with the Gaussian distribution described. The absorbance of undoped TiO2 with Rose Bengal dye is very high hence most of the light is absorbed in undoed TiO2. The absorbance of 0.25Zr1PT photo catalysis falls more due to smaller particle size among the various weight percentages of Zr and P doped in TiO2 nanoparticles. Among all photo catalysis, 0.25Zr1PT has a higher percentage of photo degradation of Rose Bengal. The percentage of degradation is higher at 50 mgL−1 than at other catalyst dosages. Kinetic studies that suit pseudo first order reactions provided the rate constant for all doped TiO2 nanoparticles.
