Copper and sulphur co-doped titanium oxide nanoparticles with enhanced catalytic and photocatalytic properties

Copper and sulphur co-doped titanium oxide nanoparticles have been prepared by the sol–gel method to develop versatile catalysts exhibiting enhanced catalytic and photocatalytic properties. Structural, morphological, chemical composition, and optical characterizations of the synthesized titanium oxi...
