Photocatalytic Water Splitting and Water purification

Carbon nitride polymers with high stability, smaller band gap and appropriate band positions gaining great interest in majority of researchers now-a-days for harvesting large abundant and renewable sunlight. The availability of various precursors and its easy synthesis protocol makes it a prime choice in the field of visible light active photocatalysts over the previously available catalysts. Because of its appropriate CBM (Conduction band minima), it has been utilized as a photocatalyst for water splitting to generate hydrogen. Due to its lower positive VBM (Valence band maxima), it is strongly recommended as a heterogeneous photocatalyst for selective synthesis of fine chemicals. Several heterostructurenanocomposites are of major interest for enhancement in the generation of either hydrogen or oxygen or both and in fine chemical production. Due to it’s rich electron density and high porosity, it can bind metals easily and been utilised removal of toxic metals as well as removal/ decomposition of organic pollutants.
