Summary: This study investigated the effects of different hydrophobic agents and pH modification on the SiO2-TiO2 composite. The results showed that the surface morphology and roughness of the coating were influenced by the hydrophobic agents. Changes in vibrational properties and self-cleaning properties were observed due to the addition of TiO2 nanoparticles. The photocatalytic activity was improved in specific coatings with the hydrophobic agent and nanoparticles. The pH also had an impact on the performance of the coatings.

Summary: Graphenic materials were used to enhance the enrichment factor for pervaporative removal of toluene from water. The synthesized nanosheets were properly functionalized and reduced. Incorporating graphene oxide or graphene oxide functionalized with butylamine/octadecylamine led to decreased enrichment factors, while chemically-reduced derivatives of graphene oxide increased the enrichment factors significantly.

Summary: A novel super-hydrophobic/super-oleophilic surface of quartz sand was prepared by constructing a silica rough structure and modifying it with low-surface-energy hexadecyl-trimethoxysilane. The modified quartz sand showed high separation efficiency in separating oil and water, with water content in the filtrate less than 0.5 wt%. The modified quartz sand also exhibited good stability and reusability, with the water contact angle remaining above 148 degrees even after repeated tests.
