Screening the effect of TiO2% on the photocatalytic activity of the Pd-g-C3N4-v@γ-Fe2O3-TiO2. The yields were determined by GC-FID analysis. Reaction conditions: The reactions were run in ethanol (3 mL) containing 4-chlorobenzaldehyde (0.2 mmol); 1,2- phenylendiamine (0.22 mmol), and styrene (30 µL, 0.26 mmol) at room temperature for 5 h.
