Metal and metal oxide nanoparticles are gaining traction in inorganic catalysis photocatalysis, driving the development of eco-friendly methods. This study introduces an cost-effective approach for synthesizing Al2O3 (NPs) using extracts derived from leaves Calligonum comosum L. The primary objective this investigation is to assess photocatalytic efficacy synthesized catalyst addressing organic pollutants. NPs exhibit a spherical morphology with crystalline arrangements, as evidenced by average crystallite size 25.1 nm XRD analysis. band gap energy determined be 2.86 eV. In terms mechanical properties, show significant potential enhancing both flexural compressive thereby making them viable choice improving performance composites. Notably, Young’s modulus hybrid composite (comprising plant material NPs) exhibits remarkable increase 34.4% flexion 78.3% compression compared alone. catalytic evaluated methylene blue (MB) cationic dye Rose Bengal (RB) anionic dye. Impressively, demonstrate degradation efficiencies 98.2% MB 90.5% RB. processes occur under solar light irradiation, contact time 120 m, maintained pH 7, temperature 25 °C. found that promising, cost-effective, environmentally friendly option water treatment.

A novel CoAl₂O₄@ZnO nanocomposite (NC) was synthesized via a green, low-cost, and simple sol-gel method using Amygdalus scoparia Spach gum. The photocatalytic efficacy of the produced NC examined for degradation tetracycline (TC) under visible light. analyzed XRD, BET, UV-Vis-DRS, FESEM, TEM, EDX Mapping. XRD analysis confirmed formation CoAl₂O₄ with cubic spinel structure ZnO hexagonal wurtzite structure. BET revealed specific surface area approximately 40.045 m²/g. band gap energy estimated to be around 3.0 eV Tauc equation. demonstrated significant efficacy, obtaining 93% in 45 min light irradiation. LC-MS identified multiple intermediate products during comprehensive investigation photodegradation mechanism which pathway. addition ethanol as scavenger led reduced activity demonstrates that hydroxyl radicals (•OH) play crucial role process. maintained stability efficiency throughout five repeated tests showed minimal reduction activity.

Abstract The study compares TiO 2 NPs synthesized via conventional chemical methods using Titanium Tetra Isopropoxide (TTIP) precursor versus an eco-friendly green synthesis approach Moringa oleifera seed (MOS) extracts. Two standard fabrication routes-sol-gel and hydrothermal were employed for both (CS) (GS) processes. as-formed nanoparticles from all four conditions (CS-sol gel, CS-hydrothermal, GS-sol GS-hydrothermal) exhibited a spherical shape pure rutile crystal structure with slight variations in mean diameter based on the technique. Optical absorptions showed bandgap energies ranging 3.14–3.28 eV 2.24–2.59 CS- GS-TiO systems respectively. lower energy of suggests higher visible light absorption, confirmed through diffuse reflectance spectroscopy where had base absorbance levels. as catalysts methylene blue (MB) dye degradation under UV sunlight irradiation. Intriguingly, results indicated that MB irradiation demonstrated superior efficiency compared to In conclusion, green-synthesized showcased excellent optical properties enhanced photocatalytic performance dye, approaching 64 %.
