Nano materials find wide applications due to their behavior at nano scale. TiO2 nanoparticles (TiO2 NPs) was synthesized using Neem leaf extract. This is simple, rapid, eco‐friendly, cheaper and green tools for TiO2 NPs synthesis using agricultural waste at lower applied temperature. Characterization of the extracted TiO2 NPs was confirmed by XRD, SEM, EDAX, TEM, HR‐TEM, SAED, and FT‐IR, respectively. The catalytic activity of TiO2 NPs was investigated in synthesis of 1,2‐dihydroquinoline derivatives with excellent yields and low cost. Purification of the synthesized 1,2‐dihydroquinoline derivatives carried out by easy work‐up of non‐chromatographic methods.
