Nowadays green synthesis is being incorporated into various technological fields to achieve more sustainable and environmentally friendly processes. By reducing the use of hazardous chemicals, minimizing waste generation, utilizing renewable resources, offers potential solutions address environmental concerns promote development in technology sectors. Herein we demonstrate an approach for fabrication MgO nanoparticles by using fruit extracts. In this current study, watermelon, Aloe vera, Jamun extracts are used as fuel nanomaterials. Prepared materials were characterized characterization techniques. Scanning electron microscopy (SEM) images porous nature material Diffused reflectance spectroscopy (DRS) reveals energy gap (4.8–4.9 eV) material. Photocatalytic degradation Direct Green (DG) dye was evaluated under UV light irradiation catalyst prepared via jamun (MgO-J) exhibited excellent catalytic activity at 84% DG better electrochemical behavior electrode compared other materials. This present work demonstrates a highly efficient eco-friendly route synthesize multifunctional applications also encourages areas.

Abstract Rising fuel security challenges can be addressed by utilizing potential and renewable energy feedstocks such as microalgae. This study focuses on biodiesel production from Desmodesmus armatus NCIM 5583 optimizing biomass productivity lipid content. Independent optimization experiments were performed to key growth parameters, viz., light intensity, photoperiod, NaNO 3 concentration. Growth conditions with 40 µmol/m 2 /s 20 h L:04 D 0.25 g/L concentration exhibited highest of 26.51 ± 1.1 mg/L d yield 45.1 0.16% (w/w). Further, CaO bionanocatalyst synthesized using waste eggshells characterized SEM, EDX, FT-IR, XRD. The results SEM EDX confirmed the structural elemental composition Ca O main elements. XRD revealed crystalline nature a particle size 28.74 nm. Lipid transesterification catalyst yielded 84 0.2% (w/w) FAME was analyzed 1 H NMR, 13 C GC–MS. presence methyl ester group, implying conversion microalgal lipids biodiesel. findings this demonstrate D. for application catalysts.
