The optical properties of the nano-structured catalysts and organic molecules were studied. The advantages of methods are short reaction times and milder conditions, easy work-up and purification of products by non-chromatographic methods. The catalysts can be recovered for subsequent reactions and reused without any appreciable loss of efficiency.}, number={1}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Teimouri, Abbas and Chermahini, Alireza Najafi and Ghorbanian, Leila}, year={2024}, month={Feb.}, keywords={Green synthesis, Nano-sulfated zirconia, nano ZnO, Nano--alumina, Nano-ZSM-5, Pyrazoles} }
