Effect of graphitic carbon nitrides (g-C3N4) prepared from different precursors on photocatalytic activity of TiO2/Bentonite Nanocomposite

The nanocomposites of g-C3N4/TiO2/bentonite have been synthesized from three different precursors (urea, thiourea and their 1:1 mixture). The variation in the thermal decomposition and condensation pathways led to the formation of g-C3N¬4 with different morphological (sheets or tubes like structures) and photophysical aspects which affect the photocatalytic activity of g-C3N4/TiO2/ bentonite nanocomposite. The composite synthesized from urea precursor was highly effective in degrading (90%) an industrial dye (reactive brilliant red) under visible light irradiation. The high activity was attributed due to formation of tubular g-C3N4 which leads to the generation of high surface area, and uniform pore distribution in the nanocomposite.
