A new method for the sustainable synthesis of various functionalized biaryls through the solid‐state Suzuki–Miyaura cross‐coupling reaction has been developed. This solid‐state protocol employs a palladium catalyst anchored on diazabicyclo[2.2.2]octane silica ferrite composite (Pd‐DDIL@Fe3O4‐SiO2). The catalyst has been fully characterized using multiple techniques such as FTIR, XRD, FESEM, EDS, elemental mapping, HR‐TEM, XPS, BET, TGA‐DTA, and VSM. The Pd‐DDIL@Fe3O4‐SiO2 catalyst has a surface area of 60.17 m2 g−1 and a magnetization saturation of 40.95 emu g−1. The TEM analysis revealed the rough spherical morphology of PdNPs having a particle size of 7 nm. The catalyst has excellent activity and selectivity towards the synthesis of both symmetrical and unsymmetrical biaryls under solid‐state, solvent‐free grinding conditions using a mortar and pestle. This method is eco‐friendly, as it is performed at room temperature without any solvents. The method employs the excellent yield of the products (90–96%) in a short reaction time (3–20 min). The desired products are isolated easily without any use of organic solvents. The catalyst can be easily separated using an external magnet and reused at least six times with an admirable change in yield. Additionally, the catalytic system has been shown to have a high TON and TOF, thus confirming its sustainability.

In the present work, an extract of Salvia officinalis leaves was used to synthesize an alumina/NiO nanocomposite by the coprecipitation method. First, the shape and surface content of the synthesized adsorbent were determined. Scanning electron microscopy images showed the production of nanospheres and nanorods with sizes between 35 and 50 nm. X-ray diffraction measurement revealed strong, high-intensity peaks, confirming the preparation of a highly crystalline alumina/nickel oxide nanocomposite. Then, the pure nanoalumina, nickel oxide, and functionalized alumina/nickel oxide nanocomposite for water defluoridation were investigated under various conditions, for example, stirring period, pH, and initial fluoride concentration. Defluoridation with greener alumina, nickel oxide, and alumina/nickel oxide nanocomposite lasted 120 min at adsorbent dosages of 0.8 g/L in a pH 7 solution. The adoption process for the three sorbents matches the Langmuir adsorption isotherm. The process dynamics were explored using pseudo-second-order and first-order kinetics. The water quality after treatment met drinking water requirements, proving the viability of using nanoparticles for drinking water defluoridation. This work confirmed effective water defluoridation in the crystalline phase using synthesized nanoalumina, nickel oxide, and their nanocomposite, which highlights their importance for future drinking water defluoridation.
