AB  - Highly ordered mesoporous silica materials (HOMMs) are widely valued for applications in catalysis, adsorption, and energy storage, but their traditional synthesis suffers from lengthy hydrothermal aging, high-temperature calcination, toxic swelling agents, and irreversible loss of the expensive Pluronic P123 template. Herein, we introduce a novel Iono Non-Hydrothermal (INH) method that completely eliminates both hydrothermal treatment and calcination. Green deep eutectic solvents (DESs) are employed in a multifunctional role as reaction medium, swelling agent, and low-temperature (120 °C) de-templating agent. The optimized ternary DES enables efficient template removal while preserving abundant surface silanol groups. The resulting HOMMs exhibit high surface area (up to 777 m<sup>2</sup>/g), uniform pore size (∼7.8 nm), and excellent structural order comparable to conventionally synthesized SBA-15. The influence of synthesis pH (adjusted by NHOH) and DES composition on pore structure and hydrothermal stability is systematically investigated, revealing that higher condensation pH significantly enhances resistance to boiling-water degradation. Importantly, simple ethyl acetate extraction of the post-synthesis filtrate allows recovery of P123 together with the DESs, establishing a near-closed material loop. A preliminary techno-economic analysis demonstrates 81–87 % material cost reduction, 50–67 % lower energy consumption, and > 32 % higher throughput compared to the conventional hydrothermal-calcination route. The INH strategy thus offers a sustainable, scalable pathway for producing high-performance mesoporous silica materials with substantially reduced environmental impact and production cost.
