Carbon Fiber Composite

TiO2/carbon fiber composite is achieved by loading TiO2 nanoparticles on biomass carbon fiber, which originates from the carbonized natural bast. The carbonized process and the loading amount of TiO2 are researched in detail. It is found that the carbonized bast fiber shows robust adsorption characteristics for TiO2 nanoparticles in aqueous dispersion, and TiO2 nanoparticles with ~15 wt.% in total weight are uniformly loaded onto the fiber surface. The photocatalytic properties of TiO2/carbon fiber composite are evaluated by photocatalytic degradation of rhodamine B and water splitting for hydrogen production. The results indicate that 90% RhB molecules could be attacked in 60 min under UV light irradiation, and the hydrogen production rate of water splitting is up to 338.51 μmol/h. The highlight is that TiO2/carbon fiber composite is easy to be recycled due to the incorporation of macroscopical biomass carbon fiber.

Surface Morphologies

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.
