Design, synthesis and photodegradation ammonia properties of MoS2@TiO2 encapsulated carbon coaxial nanobelts

Abstract Ammonia pollution poses serious threats to public health, especially in livestock. Developing an efficient method to eliminate ammonia is critical for environmental control in agricultural livestock. Herein we fabricate a one-dimensional coaxial nanobelts of molybdenum disulfide growth on titanium dioxide encapsulated carbon nanobelts (MoS2@TiO2 CNBs) by electrospinning followed hydrothermal reaction method. The as-prepared catalysts were used to photocatalytic degradation of ammonia gas, and the experiment results show that MoS2@TiO2 CNBs displayed excellent photocatalytic activity and degraded ammonia gas with 91% efficiency after only 7 min, which mainly attributed to the synergistic effect from chemical compositions and the robust banding structure. Additionally, we propose an economical, convenient, and effective in situ analysis and monitoring method for photodegradation of ammonia, which presents promising application for further development of other high efficient photocatalysts for toxic pollutant degradation.
