A rapid synthesis of quinoxalines by using Al2O3–ZrO2 as heterogeneous catalyst
Synthetic Communications
Neem gum (Azadirachta indicia) facilitated green synthesis of TiO2 and ZrO2 nanoparticles as antimicrobial agents
Inorganic Chemistry Communications
Arkivoc, 2006

Operational simplicity, use of an economically convenient catalyst, high yield, short reaction times are the key features of this protocol.
ZS-1 Zeolite as a Highly Efficient and Reusable Catalyst for Facile Synthesis of 1-amidoalkyl-2-naphthols Under Solvent-Free Conditions
Catalysis Letters, 2021

Characterizations of catalysts were carried out using diverse analysis techniques such as XRD, FT-IR, FESEM, EDAX, HRTEM, BET, and NH3TPD. Promoted as an environment-friendly protocol for the facile synthesis of various substituted 1-amidoalkyl-2-naphthols through the reaction of β-naphthol, aldehyde, and amides under solvent-free conditions. This catalyst provides many advantages such as shorter reaction times, operational simplicity, reusability, an excellent yield of the product, facile work-up, and easily recoverable. Moreover, the recovered catalyst can be recycled and reused for the next five runs without significant loss of catalytic activity.
