Current Perspective of Semiconductor and its Composites with Unusual Surfaces for the Use of Photocatalysis: Review

Recently, numerous semiconducting materials and its composites are studied for their photocatalysis applications. These materials having different size, shape and controlled morphology in micro, meso and nanoscale exhibits various important surface features having remarkable applications in photocatalytic degradation of toxic pollutants, hydrogen production and adsorbent for wastewater treatment. However different methods are followed to synthesis semiconductors, metal supported/loaded semiconductors, heterostructures, graphene based semiconductors and other newer materials. In addition, the surface morphologies of these materials and composites for its photo catalytic processes can be explained. Finally the photophysical properties of semiconductor and composite materials with unusual texture will be summarized.
