Synthesis of C–N–S co-doped TiO2 mischcrystal with an isobandgap characteristic and its photocatalytic activity under visible light

In this paper, a simple thermal decomposition synthesis route for a carbon–nitrogen–sulfur (C–N–S) co-doped titanium dioxide (TiO₂) mischcrystal with an isobandgap property for visible light applications using urea as the C, and N Ti(SO₄)₂ as S source is reported.
