Dyes Removal

A series of nanoporous carbons (NPC) Fe-C/N-900 and C/N-900 have been synthesized from one-step carbonization of 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin-Fe (Fe-TCPP) and TCPP, respectively and employed as photocatalyst for the degradation of organic dye methyl violet (MV) under UV irradiation. The optimized Fe-C/N-900 (carbonized at 900 oC for 2 h) exhibited an optimal performance in MV degradation. The photodegradation capacity of Fe-C/N-900 has been observed to be higher than that of C/N-900. The photodegradation ability of Fe-C/N-900 as a function of initial MV concentration, catalysis dosage, and pH has been also investigated. The Fe-C/N-900 material showed no apparent loss in MV degradation after four cycles. These features reveal that Fe-C/N-900 may be a promising degradant for dyes removal from water.                     KEY WORDS: Photocatalysis, Nanoporous carbons, Methyl violet, carbonization   Bull.

Self Cleaning

This research intends to enhance the photocatalytic efficiency and durability of substrates coated with TiO2-based nanocomposites under visible light illumination. More specifically, TiO2/SiO2/graphene oxide nanocomposites are successfully sono-synthesized and sono-fabricated onto a polymeric fabric through a facile one-step method. The morphologies, phase structures and optical properties of the samples are studied. The photocatalytic activity of the functionalized samples is assessed through a gentian violet stain removal test and then photodecomposition of methylene blue under visible light, and tested again after 10 washes to check on its durability. It is corroborated that TiO2/SiO2/graphene oxide nanocomposites have shown significantly better visible light self-cleaning performance than just using the pure TiO2 alone. In addition, even after 10 washes, the samples virtually maintain the functionality. Herein, sono-synthesis of TiO2/SiO2/graphene oxide represents a remarkable step forward in visible light-driven self-cleaning treatment for flexible materials and, hence, holds a great potential for commercialization.
