Development of a hydroxyapatite-based composite: Sr-doped HAp/NiO proven to be an efficient nanocatalyst for photocatalytic degradation of organic dye and photoreduction of Cr(vi)

Abstract

An efficient heterogeneous photocatalyst, Sr-doped HAp/NiO was utilized to degrade harmful Congo red dye and reduce carcinogenic Cr(vi) to less hazardous Cr(iii).
