Visible light activation of photocatalysts formed from the heterojunction of sludge-generated TiO and g-CN towards NO removal.

The feasibility of preparing TiO/g-CN heterojunction from Ti-incorporated dried dye wastewater sludge is explored in this study. Two reaction routes of composite formation were evaluated. In the initial approach, one-step calcination of dried sludge and melamine mixture @600 °C was carried out.

Synthesis and NO removal performance of anatase S-TiO/g-CN heterojunction formed from dye wastewater sludge.

In this study, sludges generated from Ti-based flocculation of dye wastewater were used to retrieve photoactive titania (S-TiO). It was heterojunctioned with graphitic carbon nitride (g-CN) to augment photoactivity under UV/visible light irradiance. Later the as-prepared samples were utilized to remove nitrogen oxides (NO) in the atmospheric condition through photocatalysis.

Facile synthesis and characterization of anatase TiO/g-CN composites for enhanced photoactivity under UV-visible spectrum.

For the purpose of atmospheric NO removal, anatase TiO/g-CN photocatalytic composites were prepared by using a facile template-free calcination route in atmospheric conditions. Considerably fiscal NP400 and laboratory-grade melamine were used as the precursor of the composites. Additionally, samples were prepared with different wt.

Preparation and characterization of TiO generated from synthetic wastewater using TiCl based coagulation/flocculation aided with Ca(OH).

This study focused on the preparation of undoped and Ca-doped titania from flocculation generated sludge. Initially, TiCl was utilised to perform coagulation and flocculation in synthetic wastewater and an optimised dose of coagulant was determined by evaluating the turbidity, dissolved organic carbon (DOC) and zeta potential of the treated water. Later, using Ca(OH) as a coagulant aid, the effects on effluent pH, turbidity and DOC removal were investigated.
