Title
Low-temperature catalytic oxidation of chlorobenzene over MnOX/TiO2–CNTs nano-composites prepared by wet synthesis methods
Abstract

Catalytic oxidation of chlorobenzene (CB) was studied over MnOX/TiO2–CNTs (carbon nanotube) nano-composites prepared by the solvothermal and sol–gel methods. Microstructures and redox properties of these composites were characterized by X-ray diffraction, electron microscopy, and temperature-programmed reduction. The catalytic activity for CB oxidation was promoted with the introduction of CNTs into MnOX/TiO2, and CB oxidation efficiencies of 90% and almost 100% could be obtained at 150 °C and 300 °C, respectively, under a gas hour space velocity of 36,000 h− 1.The high catalytic performance could be attributed to the good dispersion of active component and the selective adsorption of CB by CNTs.

Research highlights► MnOX/TiO2-CNTs composite catalysts were prepared by wet synthesis methods.► The introduction of CNTs decreases the particle size and increase the surface area of the catalysts.► The catalysts containing CNTs showed higher CB removal efficiencies in low-temperature region and had higher TOF than catalysts without CNTs.Graphical abstractFigure optionsDownload full-size imageDownload as PowerPoint slide
