Abstract

Nowadays the presence of toxic dyes in surface water has drawn much attention owing to the deleterious effects on human-beings, aquatic animals and non-biodegradability of the dyes. Much work has been done for the removal of colored dyes from polluted water by various methods namely adsorption and photo-degradation. Lately, a non- metallic, bio-compatible semiconducting material graphitic carbon nitride (g-C3N4) has taken prominence but the rate of electron-hole pair recombination is very high and insignificant visible light activity has limited its application. Thus the g-C3N4 with other nano-material composites have taken prominence in degrading dyes. The tunable band-gap of g- C3N4 provides enough scope for modification forming composites with metals and non-metallic with increasing catalytic activity.
