Abstract
Eggshell waste has proved to be one of the most valuable natural sources due to its considerable contributions to several research fields. Herein, calcium oxide derived from various kinds of eggshell wastes has been introduced using the calcination method at different temperatures. The prepared micro- or nano-particles of calcium oxide are also characterized by XRD, FE-SEM, TEM, BET, and FT-IR techniques to clarify their morphological and structural aspects completely. With mild basicity, this bio-derived catalyst has been applied to the green synthesis of chalcones via the Claisen − Schmidt condensation reaction. Ultimately, the reusability of the catalyst is examined to increase the catalyst economization.
期刊介绍:
The purpose of Polycyclic Aromatic Compounds is to provide an international and interdisciplinary forum for all aspects of research related to polycyclic aromatic compounds (PAC). Topics range from fundamental research in chemistry (including synthetic and theoretical chemistry) and physics (including astrophysics), as well as thermodynamics, spectroscopy, analytical methods, and biology to applied studies in environmental science, biochemistry, toxicology, and industry. Polycyclic Aromatic Compounds has an outstanding Editorial Board and offers a rapid and efficient peer review process, as well as a flexible open access policy.
