description | Photocatalysis is an attractive strategy for emerging pollutants remediation. Research towards the development of new, efficient and effective catalytic materials with high activity under wide irradiation spectra is a highly active sector in material science. Various semiconductor materials have been employed as photocatalysts, including TiO(2), SrTiO(3), CdS, BiVO(4), Ta(3)N(5), TaON, Ag(3)PO(4), and g-C(3)N(4). The latter is a metal-free, low cost polymer, providing high adsorption and catalytic properties, shown to be promising for photocatalysis applications under visible light. Furthermore, g-C(3)N(4) composites are among the most promising advanced photocatalytical materials that can be produced by green synthesis processes. In this paper, the state-of-the-art of g-C(3)N(4) applications is reviewed, and application perspectives are discussed. Photocatalysis tests with g-C(3)N(4) under Xenon irradiation were performed to gather first-hand information to improve photoreactor design. Xenon light spectrum appears to be a suitable radiation source to replace direct sunlight in engineered pollutants removal processes catalyzed by g-C(3)N(4), in lieu of other currently used heterogeneous photocatalysis processes (e.g., TiO(2)-UV). LED sources are also very promising due to higher energy efficiency and customizable, catalyzer-specific irradiation spectra. |
