Preparation and photothermal properties of monosaccharide carbon microspheres
From the perspective of photothermal application,carbon microspheres were prepared by hydrothermal method with xylose and glucose as carbon sources and acetic acid as catalyst.The structure and properties of carbon microspheres were characterized by scanning electron microscopy,infrared spectrometer,UV-visible spectrophotometer,X-ray diffractometer,Raman spectrometer and self-made photothermal performance testing equipment.The results show that xylose and glucose can turn into carbon microspheres that have smooth surface and uniform size under hydrothermal conditions of 200 ℃ for 4 h.Under the same carbonization conditions,the de-gree of aromatization and graphitization of xylose-based carbon microspheres is higher than that of glucose-based carbon microspheres,which makes them have better light absorption and heating properties,showing a good application prospect in the field of light absorp-tion and heating textiles.
