The effect of mesoporous carbon nitride modification by titanium oxide nanoparticles on photocatalytic degradation of 1,3-dinitrobenzene

Abstract

In the present work, well ordered, mesoporous carbon nitride (MCN) sorbent with uniform mesoporous wall, high surface area and pore volume has been fabricated using the simple polymerization reaction between ethylene diamine and carbon tetrachloride in mesoporous silica media, and then modified by TiO2 nanoparticles (Ti-MCN). The structural order and textural properties of the nanoporous materials were studied by XRD, elemental analysis, and nitrogen adsorption-desorption experiments. Photodegradation experiments for 1,3-dinitrobenzene were conducted in batch mode, the Ti-MCN catalysts were found to be more active compared to the free TiO2 nanoparticles for 1,3-dinitrobenzene degradation.
