An efficient method for assembling layered g-C3N4 nanosheets grow on 1D pore channels carbon fibers as a composite photocatalyst by ultrasound-assisted exfoliation and hydrothermal method

Abstract

A composite catalyst that layered graphite carbon nitride (g-C3N4) nanosheets adhered on electrospun carbon fibers (CFs) carrier was prepared, and this catalyst occupied the efficient photocatalytic activity. The carbon fiber was obtained through electrospinning technology and high-temperature calcination process. The layered g-C3N4 nanosheets was derived through the direct heating and ultrasonic exfoliation. After that, the g-C3N4/CFs were successfully synthesized in the hydrothermal process. In the process of degradation, composites had the capacity of degradation to different organic dyes under the UV-light irradiation, meanwhile, catalyst had excellent capacity of adsorption and a certain recycling performance. Thus, g-C3N4/CFs catalyst has potential appliance value in the degradation of organic pollutants.
