Catalytic Composite Systems Based on N-Doped TiO2/Polymeric Materials for Visible-Light-Driven Pollutant Degradation: A Mini Review

Abstract

This mini review summarizes the preparation and testing of polymeric composites with a N-doped TiO2 photocatalyst to effectively design a photocatalytic system for water pollutant degradation under visible light. In detail, the various N-doped TiO2/polymer composites reported in the literature are briefly discussed along with some examples dealing with the use of N-doped TiO2 particles, both supported on the external surface of polymers and dispersed within the structure of visible-light-transparent polymeric aerogels. Finally, the scope for future works and challenges for the commercialization of such materials are highlighted.
