Published in the Journal of Bioresources and Bioproducts, this study introduces a revolutionary mechanochemical strategy that challenges conventional material synthesis paradigms. The research demonstrates that water, when combined with mechanical grinding, can activate sodium methylsilicate to generate reactive hydroxyl groups, enabling condensation with over 40 different substrates ranging from natural macromolecules to metal compounds. The resulting hydrophobic porous materials exhibit exceptional properties including surface areas of 129–388 m2/g, yields of 66%–90%, and remarkable versatility in environmental applications. Notably, the system can directly utilize untreated plant tissues and atmospheric CO2, converting the greenhouse gas into valuable sodium bicarbonate byproducts. The materials demonstrate outstanding performance in oil-water separation with petroleum ether permeability exceeding 801 L/(m2 h), propofol medical waste adsorption rates above 85%, and dye degradation efficiencies reaching 99.99% for pollutants including Rhodamine B, Congo red, and Nile red. This work establishes a generalizable platform for sustainable material manufacturing that aligns with green chemistry principles, requiring no heating, organic solvents, or harmful catalysts while maximizing the utilization of naturally abundant renewable resources.
