摘要

A calcium vanadate apatite (VAp), in which PO43-of hydroxyapatite (HAP), Ca10 (PO4) 6 (OH) 2, is completely substituted by VO43-in the apatite framework, was synthesized. Physicochemical analysis of the VAp reveals the presence of isolated VO4 tetrahedron units with a pentavalent oxidation state. The VAp acts as a high-performance heterogeneous base catalyst for various carbon-carbon bond-forming reactions such as Michael and aldol ...
