Recently, the development of visible-light-responsive catalysts for the photodegradation of organic pollutants has captured the attention of researchers globally. The ineffectiveness and high costs associated with conventional methods and techniques used for the abatement of water pollution have forced researchers to develop effective and low-cost innovative techniques for this purpose. Photocatalysis is considered an effective protocol for this purpose. Therefore, this study was conducted for the development of the Bi2O3-NiO heterojunction as a visible-light-responsive photocatalyst for the degradation of methyl orange. Ni(NO3)2∙6H2O (Fluka) and Bi(NO3)3∙5H2O (Merck) were used as precursor materials for the synthesis of NiO-Bi2O3. After fabrication, the Bi2O3-NiO heterojunction was characterized using XRD, EDX, SEM, FTIR, and TGA techniques. Then, it was employed as a catalyst for the photodegradation of methyl orange under sunlight irradiation. The fabricated Bi2O3-NiO showed higher photocatalytic activity than Bi2O3 and NiO with 100, 67, and 46% degradation of methyl orange, respectively. The rate constant determined by the non-linear method of analysis for the photodegradation of MO in the presence of Bi2O3-NiO was 3.2-fold and 1.7-fold of the rate constant with NiO and Bi2O3, respectively. The higher photocatalytic activity of Bi2O3-NiO than of its individual components in the present study is also attributed to the separation and transfer of positive holes and electrons. The recycling of spent Bi2O3-NiO under similar experimental conditions exhibited the same photocatalytic activity suggesting the stability of the fabricated Bi2O3-NiO photocatalyst.

“…It obviously represents that; reduce the absorbance concentration of the contaminant methylene blue dye with admiration time in the attendance of Titanium Di-Oxide Nanomaterials under the Ultra violet-light bombard nation. In correspondingly, Banoth Pravallika et al [11] proposed dye removal of the Methylene blue dye in the existence of UV-light irradiation. Preliminary, recorded without Titanium Di-Oxide Nanomaterials, pollutant methylene blue did not transform comprehensively only less than 10 % small entities degradation species produced and the reaction components was monitored up to 90 min.…”

The current report, an eco-friendly to environment benign to fabrication of Titanium Di-Oxide Nanomaterials (TDO-NMs) using Drypetes sepiaria Leaves aqueous extract, during the procedure, rather than using noxious and persistent chemicals throughout the experiment. Characterization of Titanium Di-Oxide Nanomaterials was revealed using UV–Vis spectroscopy, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The stability analysis of Titanium Di-Oxide Nanomaterials was determined through dynamic light scattering (DLS), which indicated that the Titanium Di-Oxide Nanomaterials were stability around -39.4 mV and with an average size of 16.78 nm. The synthesized Titanium Di-Oxide Nanomaterials were carried out for the degradation of industrial textile pollutants dyes, such as Methylene Blue. The synthesized Titanium Di-Oxide Nanomaterials acts as a remarkable catalytic activity for the removal of environment pollutants dye degradation and promising material for the dye degradation.
