A porous glass (PG) embedded with titanium dioxide (TiO₂) was produced via impregnation of the PG with Titanium (IV) Isopropoxide solution followed by crystallization. N₂ sorption analyses revealed that the specific surface area (SSA) and total pore volume of the PG reached to 358 m²/g and 0.370 cm³/g, respectively. The adsorption capacity of methylene blue (MB) for the glasses was measured in the dark, instead the photocatalytic MB removal efficiency was evaluated by the degradation of MB under UV light illumination using a UV-Vis spectrometer. The MB removal efficiency of the TiO₂ synthesized anatase powder was only 32.3% whereas, for TiO₂ embedded PG (TiPG) it was 91.6%, and nearly complete (> 99%) efficacy was achieved for TiO₂ embedded alkaline leached PG (TiPG-AL) under UV illumination 3 h period. Better MB removal efficiency was attributed to high SSA and dispersion of nano size anatase TiO₂ crystallites within the porous structure.

通过用异丙醇钛（IV）溶液浸渍PG，然后进行结晶，制造出嵌有二氧化钛（TiO ₂）的多孔玻璃（PG）。N ₂吸附分析表明，PG的比表面积（SSA）和总孔体积分别达到358 m ² / g和0.370 cm ³ / g。在黑暗中测量了玻璃对亚甲蓝（MB）的吸附能力，取而代之的是通过使用UV-Vis光谱仪在UV照明下MB的降解来评估光催化MB的去除效率。TiO ₂合成的锐钛矿粉的MB去除率仅为32.3％，而对于TiO ₂嵌入式PG（TiPG -AL）为91.6％，在紫外线照射3 h下，TiO ₂嵌入式碱性浸出PG（TiPG-AL）的功效几乎完全（> 99％）。较高的MB去除效率归因于较高的SSA和纳米结构的锐钛矿型TiO ₂微晶在多孔结构内的分散。
