Effect of nanoparticles on structure and photothermal performance of hydrothermal carbon microspheres
Using nano-TiO2,nano-TiN,and carbon nanotubes(CNTs)as nucleating agents,D-galactose as raw materials and acetic acid as catalysts,carbon composite microspheres with light heating functions were prepared by hydrothermal method.The effects of nan-oparticles on the structure and properties of composite carbon microspheres were studied by scanning electron microscopy,Fourier infra-red,X-ray diffraction,and photothermal test.Their application as photothermal materials was discussed.The results show that the type of nanoparticle plays a significant role in influencing the particle size of carbon microspheres.Among the three kinds of composite carbon microspheres,CNTs@C carbon microspheres have the smallest particle size,the most uniform particle size distribution,and the best photothermal performance,and the coated fabric shows good evaporation performance of solar water evaporation,which has potential val-ue in the application field of seawater desalination.
