In the present study, we investigated the synthesis of fluorapatite using a pseudo sol–gel processand the chemical modification of this new catalyst support via impregnation of sodium nitratefollowed by calcination at 550 8C in order to enhance its catalytic performance. This approach wasused to obtain a bi-functional catalyst for Claisen–Schmidt condensation. Indeed, this heterogeneouscatalyst exhibited excellent catalytic activity and high selectivity for the synthesis of chalconesfrom direct aromatic aldehydes with substituted ketones at room temperature. The operationalsimplicity, excellent yields of the products and the recyclability of the catalyst are the mainadvantages of this method.
