Photodegradation, kinetics and non-linear error functions of methylene blue dye using SrZrO perovskite photocatalyst.

The degradation of methylene blue dye-contaminated wastewater via photocatalysis is an efficient approach towards environmental remediation. The SrZrO perovskite photocatalyst was synthesized using the modified Pechini sol-gel method, and characterized using XRD, FESEM, FTIR, and UV-visible spectrophotometer. Crystallite size obtained by the Scherrer and Williamson-Hall methods were 45.

Improved liquid phase exfoliation technique for the fabrication of MoS/graphene heterostructure-based photodetector.

2D nanosheets produced using liquid phase exfoliation method offers scalable and cost effective routes to optoelectronics devices. But this technique sometimes yields high defect, low stability, and compromised electronic properties. In this work, we employed an innovative approach that improved the existing liquid phase exfoliation method for fabricating MoS/graphene heterostructure-based photodetector with enhanced optoelectronic properties.

Effect of Eu Ion Concentration on Phase Transition, Site Symmetry and Quantum Efficiency of ZrO² Nanocrystal Rods.

This work report the influence of Eu3+ ion concentration on the photophysical properties of zirconia nanocrystal rods including its intrinsic quantum efficiency (IQE). A simple chemical route was employed in the synthesis procedure. X-ray diffraction results show mixed phases of monoclinic and tetragonal structures.
