Developing the NiO/CuTiO3/ZnO Ternary Semiconductor Heterojunction for Harnessing Photocatalytic Activity of Reactive Dye with Enhanced Durability

Abstract

Solar active ternary NiO/CuTiO 3 /ZnO semiconductor heterojunction were developed by alcoholic dispersion technique. As prepared ternary system and parent photocatalysts were analyze crystalline phase, surface morphology, light absorbance property, electron hole accusation parting and significant functional groups by means of specific physicochemical feature measurements. From the results, enhanced visible light photo mineralization, superior efficiency of charge carriers separation and better photocatalytic degradation of reactive orange 30 were confirmed for ternary NiO/CuTiO 3 /ZnO semiconductor heterojunction. Hydroxyl radical in the radical trapping experiments confirmed the photocatalytic degradation, which plays an important role in removal of hazardous dye from industrial effluents. This work demonstrates that synergetic effect of CuTiO 3 and NiO in which it proves to be a good option for recovering the consumption of visible light of ZnO-based materials in the ternary hybrid conduction bands.

Electrocatalytic and photocatalytic activity of CuTiO3 perovskites for complete degradation of methylene blue under sunlight irradiation

“…There were no additional diffraction peaks observed from the peaks, indicating that CuTiO 3 contains no impurities. 13 Scherrer's equation and the Williamson-Hall plot were used for calculating the average crystallite sizes of the prepared samples (Table 1).…”

“…Table 3 compares the efficiency of the synthesized 0.20 M CuTiO 3 photocatalyst with the results previously reported. 12,13 3.9.8 Degradation pathway of MB dye. The MB dye's molecular mass was measured to check for degradation and was found to be m/z 319.…”

“…A xenon lamp was used as a visible light source and only 61.12% degradation efficiency of MB dye was determined after 120 min response time. 12 G. Divya et al 13 synthesized a CuTiO 3 microstructure by using the micelle surfactant method and used it for degradation of reactive orange 30 dye and found 25% degradation efficiency in 150 minutes under sunlight irradiation. 13…”

“…The resultant solution was studied for the remaining absorption of the MB dye beneath the examination. The following equation was used to calculate the photodegradation percentage of MB (Divya et al 2021):…”

CdS Coated Mn Doped ZnO Nanospheres as Textile Catalyst: Fabrication, Physicochemical Techniques and Dye Removal Under Natural Light

“…In the preparation of Mn -doped ZnO nanopowder, 10 g of zinc chloride were dissolved in 100 ml of double distilled water. 35 To that solution, 6.2 g of sodium bicarbonate was then added in portions with vigorous stirring for several minutes. The precipitate formed was washed several times with distilled water to remove NaCl formed.…”
