Enhanced photocatalytic activity of calcined natural sphalerite under visible light irradiation
Journal of Materials Research and Technology, 2017 The photocatalytic activity of natural sphalerite (the main mineral ore of ZnS) is relatively low in the absence of sacrificial donors. Present work focuses on the improvement of the photocatalytic activity of a natural sphalerite obtained from Abuni ...
