TiO2 photocatalyst for degradation of organic compounds in water and air supported on highly hydrophobic FAU zeolite: Structural, sorptive, and photocatalytic studies

► Highly hydrophobic FAU zeolite can be synthesized by a simple two-step method. ► The prepared zeolite is highly crystalline, thermally stable and highly hydrophobic. ► Hydrophobic zeolite significantly improves photocatalytic activity of TiO2. ► A distinct correlation is found between zeolite hydrophobicity and activity of TiO2.
