“…After adding 20 mL of aqueous H 2 O 2 (30 wt.%), the mixture was allowed to react at room temperature under static condition. [76] A 300 W tungsten halogen lamp of intensity 550 mW cm −2 at maximum wavelength as visible light source was placed at a distance of 20 cm. Then, the solution was exposed under visible irradiation under continuous stirring, 5 mL the suspension was taken out at the regular time and centrifuged to remove the photocatalyst.…”

Energy and environmental stuff are two of the main worries for humanity, and nanoscience plays a key role in providing the solution. Huge nano‐research activities have attracted lot of attention in the current scenario. However, designing the material with enhanced optoelectronic properties remains the foremost challenge. In the present work, the Li doped CuO nanosheets are synthesized by the chemical route and examined in photovoltaics and environmental remediation applications. The crystallographic and optical study reveals that crystallite size and bandgap decrease with an increase in lithium‐doping concentration up to 5 mole % and beyond that a reverse trend is observed. Additionally, impedance study has shown the significant contribution of lithium‐ions to the total capacitance and resistivity. Further, the photoactivity of Cu1−xLixO nanosheets (optimum concentration of Cu1−xLixO NSs (x = 0.05)) is projected to the degradation of methylene blue (MB) and used to fabricate bulk heterojunction solar cell together with P3HT and PCBM blend, respectively. The ITO/PEDOT:PSS/P3HT:PC70BM:Cu1−xLixO (x = 0.05)/LiF/Al solar cell realized higher power‐conversion efficiency η ˜ 3.91 than their corresponding pristine device η ˜ 2.98 with enhanced photocurrent density from 9.026 to 11.56 mA cm−2. The proliferation in photocatalysts and solar cells efficiency of Cu1−xLixO (x = 0.05) is mainly attributed to the higher light absorption and lesser electron‐hole recombination. The approach for the synthesis of Cu1−xLixO NSs as potential donor material and device prototypes fabricated is completely safe and cost‐effective.

Industrialization in the current times has become extremely rapid. Some of these industries are responsible for discharging dye-containing wastewater into natural water bodies and hence causing environmental deterioration. The purpose of this research is to investigate an inexpensive and easy-to-set-up photodegradation process for the mineralization of methylene blue (MB) dye. The optimum conditions required for maximum degradation of the dye were explored by varying different experimental parameters such as the initial concentration of Fe(III) and dye, pH of the reaction mixture, nature of light sources, and intensity of ultraviolet (UV) light. Approximately 97% photodegradation of methylene blue was recorded at pH 2.30 for the optimum concentration of MB of 3.00 × 10−5 M and Fe(III) aqueous solution of 8.00 × 10−4 M when irradiated under UV light of intensity 3.31 × 10−9 Ein cm−3 s−1. Under sunlight, with similar experimental conditions, 73% degradation of the dye was achieved. This is an environment-friendly, efficient, and low-cost degradation process of methylene blue.
