In recent years, most researchers have utilized hydrothermal methods to integrate TiO₂ with graphene aerogels, thereby improving charge separation efficiency. However, severe buildup of graphene sheets will result in insufficient absorption of visible light. To address the limitation, this work directly used titanium dioxide aerogel as the framework, introduced graphene and nano-Cu particles, and combined the sol-gel method to construct a TiO<sub>2</sub>-GO-Cu ternary aerogel structure(TGCA), achieving the multi-component synergistic effect of the active components. The phase composition and mesoporous structure of the material were characterized by scanning electron microscopy, ultraviolet-visible spectrophotometry, N<sub>2</sub> adsorption test, etc. A large specific surface area of 692.9 m<sup>2</sup>/g and excellent pore structure were achieved. Moreover, under visible light irradiation, the degradation efficiency of Rhodamine B (RhB) reached 100% within 30 minutes, and the band gap was reduced to 2.75 eV. After eight cycles, the photocatalyst retained 76.18% of its degradation efficiency, outperforming most TiO₂-graphene materials.

Compared with conventional ethanol solvents, DMC exhibits superior chemical stability, effectively overcoming solvent-related limitations and providing a novel approach for synthesizing SiO₂ aerogels with high specific surface area and porosity. Methyl ethoxysilicone oil was selected as the silicon source, facilitating the homogeneous distribution of hydrophobic groups within the gel phase. Building on this foundation, secondary modification of the skeletal surface using TMCS not only enabled the successful preparation of hydrophobic SiO₂ aerogels but also significantly reduced TMCS consumption and HCl generation. This approach minimized corrosion risks to experimental equipment while enhancing material performance, offering a greener and more sustainable technical solution for aerogel production. The azeotropic distillation drying process ensured the formation of a ternary azeotrope (DMC-water-ethanol), allowing water removal from the material pores via vaporization, thereby mitigating the adverse effects of capillary forces associated with direct water evaporation. This study systematically investigated the influence of drying temperature, water content, DMC/ethanol molar ratio, and TMCS dosage on aerogel properties. Optimal performance was achieved under the following conditions: drying temperature of 90 °C, water content of 10 %, n(DMC):n(EtOH)=2:1, and TMCS dosage of 10 %.
