Surface modified nanocarbons for photodegradation of organic pollutants

Abstract

Photocatalysis is a green and powerful technology and the key factor is the efficiency of photocatalysts. This study aims to develop metal-free, visible-light-responsive photocatalysts for water remediation and solar energy conversion based on graphitic carbon nitride. Surface modification and hybridization with metal-free nanocarbons (nanodiamonds and single-walled carbon nanotubes) were employed to extend the absorbance threshold and enhance the photocatalytic efficiency of the prepared photocatalysts. The mechanism was also discussed.
